Unvanquished is a free, open-source first-person strategy game shooter, pitting technologically advanced human soldiers against hordes of highly adaptable aliens. Players can choose from either team, providing for an entirely different experience on both sides, as humans focus on long-range firepower while aliens rely instead on quick movement and stealth. The goal of each match is to destroy the enemy base, preventing members of the opposing team from spawning. Upgrades for both teams are earned by a combination of individual performance and team map control, unlocking access to more powerful weapons and equipment for the humans, and larger, more ferocious forms for the aliens.

Our project has been in development since the summer of 2011, with our very first alpha release being made on February 29th, 2012. Ever since, we have made monthly alpha releases, with each new release adding new content in the form of assets, maps, gameplay, or engine features. Our development team consists of a mix of skilled hobbyists and seasoned professionals from around the world, and we are always receptive to new team members, both from the community and beyond.

Unvanquished is a fork of Tremulous, powered by the Daemon engine. The Daemon engine that powers our game is ultimately based off Quake 3, along with features from ET:XreaL, as well as our own coding efforts. We are currently in the process of rewriting our engine into C++ for better long-term maintainability. Some of our features include:

  • A modern OpenGL version 3 compliant renderer.
  • Special effects, including bloom, rim lighting, motion blur, heat haze, and color grading.
  • Advanced texturing techniques, including terrain blending, normal and relief mapping.
  • Support for glow, gloss, specular, and physical mapping.
  • Modern libRocket user interface supporting HTML4/CSS2 standards.
  • Native Client VM support for cross-system sandboxed game logic.
  • IQM and MD5 models with skeletal animation and procedural animation blending.
  • 2D minimaps and a real-time beacon system.
  • Navmesh-based bots utilizing behavior trees.
