Play Doom (U)(Mode7) Online

I remember picking up Doom on the Game Boy Advance, a port developed by id Software and published by Activision. It was one of those releases that felt ambitious for the hardware, bringing a PC classic to a handheld during a time when portable systems were just starting to handle fast, first-person action. The screen was small, the controls were different, but it was unmistakably Doom.

You control a space marine fighting through Mars facilities overrun by demons. The goal is simple: survive each level, find the exit, and eliminate anything that moves. You explore maze-like corridors room by room, collecting keycards to open new areas and managing a limited arsenal that includes a chainsaw, shotgun, and rocket launcher. The pacing is relentless; enemies pour out from dark corners, and the cramped level design keeps tension high. It feels raw and immediate, like you're barely holding back the darkness with every shot.
