Rebound Invaders from Outer Space Back from the arcade days when classic arcade games ruled we bring you Rebound Invaders from Outer Space. Your ship is equipped with the latest high energy weapon - The Lightening Plasma Ball. Lightening plasma balls are great, they bounce everywhere until they destroy a ship or fall off the bottom of the screen. Great, you can shoot around corners and have lots of bullets in action at the same time, one small design flaw though ... they will also destroy your ship! The aliens are fighting back: They have developed a light saber force field to bounce your plasma balls right back at you - take care not to shoot yourself in the foot! So there's lots of action in this arcade style shoot'em up. You'll need fast reactions, and lots of skill to defeat the "Rebound Invaders from Outer Space". Tilt your screen to move, touch the screen anywhere to fire. If you're not a fan of tilt controls, pop in to the setting and you've find an option to enable on screen controls. Download Rebound Invaders now, its Free.
