Chex Quest was a total Doom conversion released all the way back in 1996 as a promotional game for Chex cereal. Despite all odds and the usual tie-in game curse, Chex Quest ended up not only being a good bit of fun, but also popular enough that it still has a small cult following to this very day.

So if you're curious about what exactly it has to offer, or if you're simply looking for a bit of a nostalgia trip, you'll be glad to hear that a modern HD remake of Chex Quest has now landed onto Steam. And best of all, it's entirely free to grab!

In terms of features, Chex Quest HD brings greatly overhauled visuals and gives you a chance to play as one of the six unlockable characters in both singleplayer and split-screen multiplayer. Keeping in line with its promotional nature, the codes for the various characters can be found on either cereal boxes or on the Chex website. As of right now only one code is available, but the rest should be coming online soon enough.

Have fun, and I'll leave you with one of the trailers:
