In this Tower Defence game, creeps move on multiple paths, and have 4 different spawn portals! So, you must be able to build your towers strategically to defend your factories. As the game progresses, many new towers and enemies are unlocked. You can always come back to continue your game, as the game is automatically saved every wave.
Enemies advance to your factories by the highlighted path. Build your towers on grass to protect your factories. When a enemy enters a factory, it is destroyed, or reduces a level.
Campaign: 50 easy waves for beginners. Towers are unlocked slowly throughout the game.
Endless: Unlimited waves, play to the death!
Survival: You start with 4 level 5 factories, but you can't build any factories. Defend untill you lose all your factories.
