Wolfenstein: Enemy Territory

OLD GAME BUT FUN AND TEAMWORK

This looked like a lot of fun and still could be a lot of fun there's only two main things holding it back: There was a bug (at least for me) in accessing the anti-cheat servers (I kept hitting enable and it kept saying they weren't enabled). There is a heavy XP system that ruins the fun for intro players and makes no sense whatsoever in a game like this (either realistically or gameplay wise).

The exact definition of gog, spend so much time om it in my fifteen, so glad to found it 18 years later with some real people on it! of course my stats aren't good as before, i'm now the weak XD

Vibrant Multiplayer community also.

The perfect balance of bullet-spongy enough that who shoots first isn't guaranteed to win yet not too bullet-spongy that you can't get multi-kills. The perfect balance of not spawning so close to people that you immediately die when you spawn yet you have that quake movement capability to get to the action fast. The perfect balance of greatly rewarding your skill but allowing you to be useful to your team if you aren't the best player. Various servers with their own configurations so you get it how you prefer it. Glorious headshot sounds. Even Splash Damage themselves haven't been able to top their own gem yet. Do yourself a favor though by looking at ETLegacy instead. It is an actively developed fork that is still improving the game after all these years, and is compatible with the original.
