The game begins on planet Tenzan. Here you must complete the Tutorial missions. You will only have to do this once when starting a new game. The rest of the times you start at the beginning. If you want to go back to the Tutorial missions again after completing them they can be access from the main screen when the Tutorial section is unlocked. This happens after the first time you beat it. I am not going to go into any detail on these since the game itself tells you what To do already. I will just list the conditions.

Winning Conditions: Build a base.
Losing Conditions: None.

Winning Conditions: Create Labor Units and build a Warehouse.
Losing Conditions: None.

Winning Conditions: Recycle and collect 100 Lasercrystal.
Losing Conditions: None.

Winning Conditions: Salvage 3 wrecks and build a Lab.
Losing Conditions: No more than 3 wrecks can be salvaged (if you wait to long to gather the wreckage it will decompose and you will lose).

Winning Conditions: Eliminate all monsters!
Losing Conditions: No allied units survive.

Winning Conditions: Build a laser base.
Losing Conditions: Allied base destroyed.

Winning Conditions: Destroy all enemy units!
Losing Conditions: Allied base destroyed.

After all of this you will have to choose whose army you will lead. There are three choices. Leon, Trampler and Minos. The missions will take place on three different planets. The missions on each planet are the same no matter who you play as so I will just do them by planet.

You will play planet Lichen if you are the Minos or the Leons. The Tramplers are the opponents. Not as hard as scorch but not as easy as Ravine.

Winning Conditions: Eliminate the enemy units!
Losing Conditions: An enemy unit reaches the target.

Get some long range units to start with. Take those and go blast up the enemy units. Make sure to bring along a labor unit to salvage their parts.

Winning Conditions: Lead five units to the target point!
Losing Conditions: Less than 4 units survive.

Start by going up the far left side. Take out the enemy there and go all the way up to the top. Now move along the top, take out the next three mechs you come across one at a time. Continue along the top until you get to the end. Go down to the target area.

Winning Conditions: Destroy the new enemy unit and collect parts!
Losing Conditions: Enemy units arrive at target or allied based destroyed.

The enemy doesn't seem too eager to start heading to the target point so you don't have to rush too much. Get your labor units mining resources and build a factory. Send out your starter units with a labor unit and start taking care of the enemy units. Get the ones along the bottom first. Then work your way up. Make more battle units and labor units as necessary. You have to salvage every last enemy unit to win this so don't let even one decay.

Winning Conditions: Guide 10 allied labor units to the target.
Losing Conditions: Allied base destroyed.

At the start you want to build up your base area. Get the labor units built and start making a fort, get your tech level up to make laser towers. Build the strongest units you got to escort the labor units to the target area. Destroying all the enemy units will just cause reinforcements to come. When you are ready go along the bottom of the screen. Don't send all your mechs in one big group. The mechs are stupid and they will all just end up running into each other and going nowhere.Send the battle units out first to destroy the first group of enemies, then send in the labor units. Send out the battle units again to take out the next group of enemy units and the factory. Now send the labor units to the left end of the screen and have them go straight up to the target. You may need to distract the two enemy units that are in between the bridge and the target so they don't spot you labor units and take them out before they get to the target. Just send over your battle mechs and the labor units should get to the targets with out a problem.

Winning Conditions: Collect 500 Materialrock! *Not total. Must say 500 on screen.
Losing Conditions: Allied base destroyed or all allied labor units lost.

First build a factory and get your military Level up. Once the factory is built get the labor units mining the near by Energysand. Get the factory to build as many of whatever military unit you want. Once the Energysand is gone move all your units down to the energy crystal and build a warehouse to start mining it. As soon as you do this the enemy will send a bunch of units over so get prepared for a fight. After they have been destroyed you will probably need more battle mechs so while the labor units plunder that are build up on battle mechs. don't bother with the energy crystal by the monsters. No point in bothering them unless you really need it. Once you have everything there move over to the place with the material rock. Send over the battle units first to guard the area then send over the labor units to build a warehouse and start mining. The enemy mechs there shouldn't bother you but if they do just take them out as fast as you can and try to mine all you need before the reinforcements get to be too much. Don't destroy the enemy unless you have to. Get the Materialrock and be done with it as soon as possible.

Winning Conditions: Eliminate the enemy units.
Losing Conditions: Allied base destroyed.

Leave the monsters alone for now. They will make a good obstacle for the enemy. Just build up your base area and battle mechs. Laser Towers are nice to have as well. Once you feel you have a large enough Mech Death Squad its time to take the offensive. First go to the island at the bottom of the screen and wipe out that group of enemy mechs. Then work your way east and wipe out the remaining enemies. Don't worry about the buildings. Just take down the units and the mission will be complete.

The Minos are on this planet. You will battle them here as either the Leons or Tramplers. This is the easiest of all the planets.

Winning Conditions: Destroy the enemy warehouses in less than 15 minutes.
Losing Conditions: Time expires.

I usually like to start with 3 close range units and one long range. You will have only 15 minutes to do all of this but you should have plenty of time left over. First you need to do two things. Get a base built and send your battle units off to destroy the warehouse and its guard that are to the direct right of the starting point. Once the base is built make a couple more labor units and have all them start bringing in resources. I wouldn't bother with the Energycrystal unless your long range unit gets destroyed. Just get the Energysand and the Materialrock. Once you have enough build a factory so you can make more military units. While doing this send your battle units to the next ware house to the right and destroy it then move north to the next one and take it out. You might be low on units now so regroup with the ones you made and take out the last warehouse at the top.

Winning Conditions: Lead five allied units to the target destination.
Losing Conditions: Less than 4 allied units survive.

Pick all Abyss units for this level. They will be able to pick off the monsters before they get a chance to fight back. First head down to where the labor units are. Take out any monster that are in your path. Once you reach them send two off to where the destination is to clear a path. Once that is done Move the labor units to the destination with the two other battle units.

Winning Conditions: Destroy the Train.
Losing Conditions: Enemy Train survives or allied base is destroyed.

Start with four close range battle units. You don't really need the long range ones in this mission. Get your labor units going right away gathering materials and get a factory built to make more close range units. Send the ones you got now out into battle. Make sure to send one labor unit with them to pick up the wreckage of the enemy mechs to get a new piece of equipment. Bust up all the enemy mechs and then go after the train. Send in reinforcements as needed.

Winning Conditions: Lead new parts transport to the allied base.
Losing Conditions: New parts transport unit lost or allied base destroyed.

First you need to get those transport trucks moving. They are sitting ducks right now and they have a bunch of enemy units headed there way. Go down. You want to get them below where the monsters are. Not that the monsters will battle the enemy units(lame…) but its the safest spot for now. Meanwhile have your labor units build a factory and start gathering resources. Make some close range units and clear out the enemy units that are to the left of the base. Take out the ones on top first. Get your transport trucks though there and to the base. You may want to salvage some of the enemy units for parts as well.

Winning Conditions: Protect the Materialrock mining site.
Losing Conditions: Enemy reaches Materialrock mining site or allied base is destroyed.

This mission is incredibly difficult. They key to winning is laser towers. Put three starter units to guard the left valley and two to guard the north valley. Now go and mine the Lasercrystal and the Energysand that is below the base. While doing this get your Technology Level up. As soon as that level is up build a Laser Tower in front of the material rock. This should hold off the intruders but you still will want to build more. Soon after all the enemy units will be destroyed.

Winning Conditions: Eliminate the enemy units!
Losing Conditions: Allied base destroyed.

First get your Tech Level up so you can build laser towers. Next start gathering resources and build a warehouse for the Lasercrystal and Energysand to the left. Once you have your tech up start building a wall of laser towers. Also set up a couple labor units to do repairs on the towers and salvage the enemy remains. Then just sit tight and let the enemy come to you for laser tower death.

This is the hardest of the three planets. You will be fighting against the Leons here. Mostly just large clashes of battle mechs against battle mechs. Minos and Tramplers play on this planet.

Winning Conditions: Eliminate the enemy units before the rail road is complete.
Losing Conditions: Rail road is completed or allied base is destroyed.

First get your labor units gathering resources. Get a factory built right away and get ready to start mass producing units. Send your starter units north and take out those three up there. You have some breathing room now. Build a warehouse now up there and start mining for more resources. Get those battle units produced and head out to take out the enemy. Make sure to send a labor unit with you to salvage there metal corpses. Just whatever you do don't take too long. You can lose this level if you take your time. The only real trick to winning is being quick.

Winning Conditions: Destroy all enemy labor units!
Losing Conditions: Enemy labor unit reaches the target.

I haven't been able to come up with a really good strategy for this level. Just get your starter Units and start busting ass. Slaughter the labor units as fast as you can.

Winning Conditions: Eliminate the enemy units!
Losing Conditions: Lava dam destroyed or allied base destroyed.

First build a base and start mining. Get your Tech and Military Levels up so you can build the laser towers and good mech units. Get your starter units to the dam and build some lasers towers over there. Should be safe from attacks now. Get a factory built and start pumping out the mechs. When you feel you have enough go take care of the remaining enemy units. The ones standing by the laser towers you need to lure away from those towers or you will slaughtered.

Winning Conditions: Lead five neutral units to the target!
Losing Conditions: Less than four neutral units survive.

This mission is extremely hard. Pick your strongest and fastest units as your starters. Just go along and grab the labor units as fast as you can and get to the target. All you have to do to get the labor units is walk by them to gain control of them.

Winning Conditions: Collect 500 Lasercrystals! *Not total. Must have it say 500
Losing Conditions: Allied based destroyed.

This one can be frustrating. You need to get your tech level up and have a tower guarding your base up as soon as possible. Make a factory to make some extra battle units as well. The enemy is going to raid your base and take it out as fast as they can. Just defend your area until there are no more enemies. This will cause two enemy reinforcements to come out at a time. Have your labor units run to the crystals then run back to the base. As you do this build more towers. Eventually you will have mined the 500 needed. Remember to do repairs on your towers as well. To the bottom right you will find more Materialrock and Energysand. You may want to build a warehouse when you have the resources and the time somewhere close to the Lasercrystal. Lastly, watch your mechs. They get hung up on edges, corners, nothing… and even go the wrong way at random. You have to keep a close eye on them all the time. Even watch the enemy mechs. They get stuck sometimes too and they can get unstuck and come around a side you are not watching.

Winning Conditions: Eliminate the enemy units!
Losing Conditions: Allied base is destroyed.

The most difficult for last, of all the missions in the game. The enemy gives you no time to build up defenses or anything. You want to start with your strongest mechs. Start your labor units working and get your tech level up as fast as possible and build laser towers. Eventually the enemy raids will taper off and give you time to build an attack squad. Once you do storm the enemy.
