Turtle Arena is a free and open source cross-platform third-person action game using the Spearmint engine (version 0.5). Turtle Arena is multiplayer oriented with multiple game modes that can be played in splitscreen, over a network, and with bot players.

Turtle Arena was a continuation of my project to create a Ninja Turtle game which started in 2006; originally based on Sonic Robo Blast 2 [Doom engine] and later an original engine. Development using the Quake 3 engine began in 2008.

I primarily developed Turtle Arena (programming and art) from 2008 to 2012, with an update in 2017. I made all of the graphics, models, and level textures. I decided to create new original characters in 2011 but creating the 3D models didn’t happen. It’s kind of just an embarrassment I want to sweep under the rug at this point (2024).
