As far as remasters go I recommend a few tweaks before you start Blood Fresh Supply. Switch from DX 11 to Vulkan. Set FPS to max. Turn off V-Sync. I had horrible stuttering before I switch to these settings. Finally turn off slope tilting (Otherwise the camera angle gets weird going up and down ramps). Now on to the game itself.
I have no nostalgia for Blood or most 90's shooters (Half-Life 1 and Quake 3 are the only exceptions) but I've definitely become a fan of them. Over the years I've played and beaten Wolfenstein 3D, DOOM 1, DOOM 2, Star Wars Dark Forces, Duke Nukem 3D, Quake 1, Turok 1, Turok 2 and obviously Half-Life 1. Now that I've finished all of Blood I can confidently say it goes toe to toe with Half-Life 1 as my favorite 90's shooter. Blood's horror aesthetic stands out from the crowd of traditional sci-fi settings these shooters tend to go for. Caleb is my new favorite FPS protagonist (yes even over the modern DOOM Slayer). It's nice to play as a character that's having as much fun throwing dynamite as I am with his psychotic laugh. Blood has the most satisfying gunplay of any 90's shooter. The sawed off shotgun in this game is legendary (remember these guys would go on and develop FEAR so they know their shotguns). The rest of the arsenal has that sweet combo of being creative, fun and useful. Blood's levels are huge and have a ton of secrets so it nails the exploration aspect 90's shooters did well. Blood is definitely challenging. I don't know if it should be your first 90's shooter because of that. Play some of the modern boomer shooters that are inspired by Blood first to get your bearings (DUSK or Cultic). Even boomer shooter veterans will get tested here. The hit scan cultist enemies have an infamous reputation for a reason. The game will gladly throw cheap ambushes at you. Once you get the full arsenal the game does get easier sort of. Overcoming Blood's difficulty is part of the joy especially when you master your dynamite throwing skills. In the end Blood is just so satisfying to play. If you want to be tested with your old school boomer shooter skills look no further.
