Unvanquished

Unvanquished is a free and open-source multiplayer first-person strategy shooter that pits two radically different sides against each other: technologically advanced human soldiers and rapidly evolving alien creatures. Developed by the Unvanquished team, the game builds on ideas originally associated with the Tremulous and Quake traditions while expanding them into a much more ambitious asymmetrical strategy experience.

The basic objective sounds familiar: destroy the opposing team's base, but the way you get there is what makes Unvanquished interesting.

Humans and aliens don't simply have different weapons and character models. They fundamentally approach the battlefield differently. Humans rely on conventional firearms, armor, deployable structures, and carefully constructed defensive positions. Aliens are faster and more mobile, can traverse walls and ceilings, and use biological abilities to overwhelm human positions. The result is a match where the two teams can feel like they're playing completely different games.

Both sides also have a commander-like strategic layer. Players can construct and upgrade structures that provide resources, defenses, spawning points, and technological progression. Destroying an enemy base isn't simply a matter of shooting everything you see, you need to understand the opposing team's infrastructure and figure out how to dismantle it.

The alien side evolves through a progression system that allows players to unlock increasingly powerful lifeforms. A small, fast alien might be ideal for scouting and harassment, while larger creatures can become terrifying frontline threats. Humans, meanwhile, gradually gain access to more advanced weapons and equipment.

This creates a fascinating tension between FPS skill and RTS-style decision-making. A player can be an excellent shot and still lose because their team has neglected its economy or allowed the enemy to establish an overwhelming position. Conversely, smart construction and coordinated attacks can compensate for individual mechanical weaknesses.

The open-source nature of Unvanquished is another major reason we like it. The project provides access to its source code and assets, allowing the community to contribute, modify, and build upon the game rather than simply consuming it as a finished commercial product.

And importantly, it remains a multiplayer game designed around teamwork. Communication, positioning, base construction, resource management, and coordinated pushes all matter.
