Rebound Invaders 2 :- The Breakout Our game testers enjoyed "Rebound Invaders from Outer Space" so much that we just had to make a sequel. Hopefully our customers in the real world will enjoy it as much! So here we have another retro style arcade classic, think of it as a combination of a space shooter meets breakout. You still have your trusty blaster with unlimited fire power, but this time the aliens have floated repulse blocks in the depths of space. Your bullets will destroy these bricks, but take care as your lightening plasma balls will bounce right back at you! To progress to the next level you'll need to clear all aliens and blast all the bricks. Later levels feature rotating and moving force fields and of course lots more aliens to blast. This is not an easy game, it will take all your skill, quick reactions and just a bit of luck to defeat the aliens in "Rebound Invaders 2 - The Breakout". Remember its free so download it now, and of course be sure and check out the original if you've not downloaded it yet. Thanks for looking, now get blasting!
