Blood is an absolute treat. Armed with a massive selection of weapons, you're tasked with surviving a legion of killer cultists and hell-spawn, as protagonist Caleb makes his way to get revenge on his master. The level design is some of the best in the genre, with some jaw-dropping setpieces, especially for 1997. Character art and texture work is bursting with detail. Every weapon is useful and satisfying, only further complimented by the diverse rogue's gallery.

Is this the best classic shooter of all time? I think so! Personally, this feels like the Super Mario World to DOOM's Super Mario Bros. 3. If you haven't played this yet, what are you waiting for? For your first playthrough, I'd highly recommend enemy damage at "Pink on the Inside", and everything else at "Lightly Broiled". Enemies will still punish you when you're careless, but you won't have the weakest fodder devouring your entire health bar with a stick of dynamite every few minutes.
