Classic Game Room presents a CGR Undertow review of Xenon 2 for the Game Boy developed and published by Bitmap Brothers. In this arcade-style shoot ‘em up, players must fight alien creatures and save the universe! Okay, so it’s not the most original game in the world, but Xenon 2: Megablast is still an excellent shooter. Originally released for the Amiga and Atari ST, the game was released for the Game Boy a few years later. And even though this version is somewhat simplified for its platform, Xenon 2: Megablast retains its fun shoot ‘em up gameplay. Players can purchase power-ups between levels to improve their ship and add to their firepower, a key to defeating these disgusting alien scumbags. Xenon 2: Megablast is a single-player game on the Game Boy. This video review features video gameplay footage of Xenon 2 for the Game Boy and audio commentary from Classic Game Room's Derek.
