I've had a hankering for some old-school shooters and have played all the big names over the last year for the first time: Doom 1 and 2, Quake, Dark Forces, Half-Life, etc. as well as modern titles like the New Blood games. Honestly, this has been the most enjoyable by a good margin. The level designs are so clean (even though the aesthetics are dirty), each chapter is distinct, and it doesn't take itself seriously with pretty ridiculous bosses and obstacles. Highly recommend for anyone itching for some great 90s-style shooting!
