Doom on the Game Boy Advance is a surprisingly good port of the classic FPS, managing to retain much of the feel and atmosphere of the original despite the hardware limitations. While the visuals are understandably downgraded and the controls take some getting used to, the core gameplay of blasting demons remains satisfying. It's a testament to the strength of the source material that it still holds up on such a small screen. The addition of exclusive multiplayer maps is a nice touch for those who can wrangle up friends with GBAs.
