Energy InvadersAuthor : Bubblebox - 8 424 plays
Build an invincible army and wipe out the alien forces before they annihilate the whole of civilisation. Energy Invaders is a real-time strategy game, where the aim is to put together troops, command them during battle, and build towers as you gain ground. The game’s mechanics are similar to those of other PC games, such as Starcraft and victory depends on your ability to manage several tasks at once, your decision-making skills and your speed.
