You open the door on a room full of Zombies and Succubi and... four barrels with little bombs on them(!). You lob a stick of dynamite into the room and BOOM KABOOM giblets and blood and bones fly EVERYWHERE. So viscerally satisfying... This is a bit of a niche game to be fair but if you loved Wolfenstein or DOOM '95 then this game will be right up your alley. There is a great variety of monsters and weapons and skills for this type of game but the outcome feels like a well thought-out mesh of elements. In particular I like the 'feel' of the weapons and the way the skills modify them. There are a ton of levels with different atmospheres and monsters for each world and huge boss fights. The music gets pretty repetitive but this is a minor gripe. TL;DR Rock-solid retro FPS with a huge amount of variety and replayability and its only $12 bucks.
