space to fire arrows. Your Powerups e - creates mega forcefield outside the tower for 0.6 seconds which can do up to around 3000 damage to the boss tank, if you place it at the right time f - gives pink background for 0.1 to 0.7 seconds which harms the boss tank and does up to 2000 damage to the it. g - green arrows, arrows have a 4x damage increase for 1.9 to 4.3 seconds. Boss Tank's Powerups Rage Mode - once the boss tank's health goes under 1000, his damage and movement speed increase. Arrows - once the boss tank goes into rage mode, two arrows shoot out which can do up to 800 damage. Plasma Ray - once the boss tank goes into rage mode, a plasma ray comes out and completely wrecks. It is good strategy to save a powerup or two for when the boss tank goes into rage mode. hope you like! jmozzyathena.
