Mines: Create huge mine field. Gun Buddies: Many random turrets Nukes: Can kill you underground. Guided Missile: Larger, stronger, but slower missile. Health and Turbo: No increased effect.
Hint: Defeating enemies quickly: Use this trick when attacking a strong enemy, wall, ect. Choose a tank that shoots one shot at a time (M1 A1, Goliath, etc.). Get some Swarmers and fire your main weapon and the Swarmers at the same time. Make sure to be at close range so all the Swarmers hit the enemy. This is a very helpful when killing a enemy very fast. It is also effective for killing Goliath and going through walls quickly.
