Chex Quest (1996)
Platform: MS-DOS, PC
Publisher: Digital Café
If while playing Chex Quest things start to feel familiar, that's because they should. Rather than going through all the trouble of designing a game, General Mills completely reskinned the original Doom, slapped on a few animated cutscenes and called it a day.
Sure, they may have changed the setting from Mars/Hell to a cutesy space station and all the enemies from demons to quirky phlegm monsters, but the game is still the same. The biggest difference between Chex Quest and id Software's game is that rather than using shotguns and chainsaws to defend yourself, players are given a "zorcher" which teleports enemies away. There's no word on what happens to the Chex Warrior's armor if you leave it in milk too long though.
