Unvanquished is a fast-paced, futuristic FPS with RTS elements, pitting technologically advanced humans against hordes of highly adaptable aliens. The player can choose from either team, providing a fresh gameplay experience on both sides of the conflict. The game is under highly active development, with a new alpha release being made at the beginning of each month.
Best open source shooter out. Great gameplay, good graphics, great balance, lots of fun guaranteed. Very promising, hope to see it develop more and more.
