Star Wars Republic Commando! Every now and then people talk about it, but it is a shame it isn’t mentioned more. I actually just replayed it, I’d almost say it holds up today with the remaster mod and the rc patch. There is also a very cool mod called “slightly remastered” which adds stuff like 3rd person scripted animations and scripted kill cams, it makes you feel like a badass! Aside from that, I’m also surprised nobody in the boomer shooter enjoyer crowd talks about Cube 2: Sauerbraten, which is a very fast paced arena shooter. The only server that is consistently active uses one shot rifles that have enough recoil to do trick jumps, very fun to hop on for a few hours
Make sure to enjoy Blue Shift as well, it is in the workshop!
