BZFlag

If tanks had jetpacks, you’d get BZFlag. This open-source multiplayer game is about zipping around 3D arenas, blasting opponents with lasers while gravity casually looks the other way. It’s been around for decades, and its community keeps it alive with maps, mods, and an endless supply of chaotic matches. The graphics may be simple, but the gameplay is timeless: point, shoot, dodge, repeat. It’s like digital capture-the-flag on steroids, with enough chaos to keep you grinning for hours. A cult classic that proves sometimes fun doesn’t need polish, just explosions.

“BZFlag is a 3D networked multi-player multi-platform tank battle game. It runs on Windows, Mac OSX, Linux, BSD, and other platforms. It was one of the most popular games ever on Silicon Graphics machines and continues to be developed and improved to this day.” - Chris Schoeneman

Review by Game Hippo:

“BZflag is a network-based multiplayer tank game in a 3D world of geometrical primitives. The rendition of the 3D word is rudiment yet fully functional that provides fun combating with and against other players. This is an online game only, meaning that you need to be connected to the Internet to partake. In the game menu you have to connect to a game server (there are several active to choose from), and select a team. As a piece of trivia, the first Windows version (1.7d9) was released in March of 2000.“
