It turns out Dante was wrong about the whole Hell thing. Rather than consisting of nine circles (each more circular than the last), Hell is actually more of a straight ride down - a 99-level tunnel punctuated by the occasional boss fight, and with Hell itself waiting patiently at the end. Either way, I'm not convinced it's worth a visit - the museums are terrible - but that hasn't stopped the be-hatted, moustachioed dude from 99 Levels to Hell from diving in. His game is a roguelikey platformer with destructible terrain, guns, gore and plenty of demons trying to kill you; if you're a fan of Spelunky, you're probably downloading it already.
99 Levels to Hell is good with numbers; in addition to the game's 100 levels (I assume Hell is #100), it also boasts of 25+ monster types and 50-odd weapons and power-ups. Because this a roguelike, you can expect shops and casinos (wait, is that a RL thing now?) to make an appearance as well, on your procedurally generated journey to Satan's sub-sub-sub-sub-sub-basement flat.
99 Levels to Hell is available for $9.99/around £6.99. Here is the game's infernal launch trailer:
