Marathon

It's not a for everyone, but the atmosphere and gameplay are very good. The movement and gunplay are top-notch, and it feels a lot like Apex Legends in how it handles with a lower TTK. End-game maps are very fun to run and to PvP, so if you're into PvP shooters I recommend this game. FWIW, I'm someone who dislikes extraction shooters, but this one is the only one that's gripped me. Additionally, the art-style is sick. If you're a casual player, I'd recommend doing some research and trying it out on a free-week/2 hour return window. I wouldn't say it's extremely sweaty compared to something like Counter-Strike, but the maps are pretty complex and have a higher learning curve. However, gunplay is not very difficult and there are some shells (characters) that can help you sneak around the map easier.
