Hunt: Showdown is also another good option. It is not the same timeline, it is set in 1890's Florida swamps, but as a Battle Royale without region limitations or anything forcing combat, it is a great game to stalk your prey or go for close quarters combat. Ballistics and medical system is rather simpler yet still very effective in how encounters go down, and also no inventory hassle.

Slower fire rate, no extraction point campers, all kinds of weirdos doing all kinds of shit that makes no sense but make every round somewhat unique and memorable. 500 hours in with 2 buddies in a year and the game still feels fresh without shoving new weapons down every month.

Also no progression hassle. 99% of the weapons can be utilized on every round, just gotta consider how you play with them and how to play against other hunters' weapons.

It is not something that can scratch the S.T.A.L.K.E.R. itch, though.

Gray Zone Warfare looks really cool and has similarities to tarkov, but the overall gameplay loop is pretty different. It's a much slower and less PVP focused game.

Arena Breakout: Infinite is an upcoming game that is much more similar to Tarkov
