Top 9 C++ fps-game Projects

openspades

6 1,098 2.9 C++

Compatible client of Ace of Spades 0.75

Project mention: Open source Diablo 1 engine – DevilutionX 1.5.0 released | news.ycombinator.com | 2023-06-17

Ace of Spades is one. I usually play with the OpenSpades client[1], but there is also Betterspades[2], and probably many other clients I don't know of yet. There are usually about 10-50 players online on the public servers listed on BuildAndShoot[3], variable depending on the time of day and mostly from Latin America it seems.
One can host the game with piqueserver[4]. I'm not sure if one can still host with the original Ace of Spades server, but the game was 'shut down' in 2019 so maybe not.
