2.6, this one need to be fast, quickly put up 3 fusion core and upgrade the starport to make it build bomber, if you have leftover materials, make the fighter into advance fighter ( the first upgrade ) and put up some defense along North West side of your base. your bomber will do all the work.
3.1 to 3.5, put up laser as fast as you can, as many as you can ... you will NEVER lose.
2.5, you need to quickly build 3 fusion core as fast as you can, then put up 4 autogun in 4 direction around your base, make sure it's not too far apart. after that, put freezer right behind the autogun in 4 directions. After you got all those, wait to grab one material generator and starting to put heavy laser to each side of the autogun, while doing that, if you have too much energy, use it to build healer station. when the infector starting to arrive with the battleship, make sure you have heavy laser to counter it ( autogun's range is not enough ). If you get rid of the infected building in time, you will be fine.
2.3, starts with 2 fusion core then quickly build auto gun to cover each gauss turret, after that, put 2 to3 freezer behind the line then put 5-6 more autogun in a line in front of your base, the rest is up to thor missile.
2.4, start off with 1 more fusion core then quickly put heavy laser on the right side of the base then follow by freezer on the left side of the base. after that, put more heavy laser on both left and right side of the base, then gather some materials and put up 3-4 thor missile turret and you're good to go.
*** CAUTION : SPOILER ALERT ***
1.1-1.6 is easy enough, you guys prolly finish it on your own
2.1, starts with 2 fusion core then starts heavy laser, the rest will be easy.
2.2, starts quickly with 3 fusion core, then autogun around the north-east part of the base, if the heavy laser to the right did not get conquered, build autogun right next to it, once you have about 5-6 auto gun in place, put 2 freezer behind some of them. from that point on, concentrate on your resources then build the thor missile to finish the game.
Ah! finally i beat the last boss, Way to beat the last boss > use normal fully upgraded bullets ( spray ) > if the boss use Bug Spray Attack, stay on one of the lowest spot on the 2/3 to the right side and stay there, keep moving with the flow .. you will get hit but not enough to kill you. > if the boss use ROCKET spray, move in "U" shape from side to another side but go through the lowest center then rise up on left/right side and repeat, if you do it fast enough, you will be able to dodge the rocket and if you practice enough, you won't get hit at all. > If the boss use plasma spray, find the biggest gap in between the cannon and stay there ( easiest to dodge)no HP lost here either. > If the boss do spray with bullet shot, stay calm and stay at the lowest part of the map, and dodge from left to right before the spray of bullet will arrive, find the gap in the bullets and stay still. if you do this right, you won't lost any HP either. gimme +s if this help !
to create 6 explosion, upgrade the rocket to level 3 then shoot it under the "train" where supposedly 3 cars under there .. kill all 3 cars make it 4 explosion then you explode yourself along with any other car ..
Bug Found : When you conquer the map ... the resident house must be build first (?) or it will steal all your food and money then said " Insufficient food + money " so they move out and all your food + money will be gone lol
