Army 21 is an online action-strategy team combat game featuring base warfare, with co-op and versus game modes. Up to 60 players in 6 teams compete to defeat the other teams by building and defending their own base, and by destroying the bases of the opposing teams. Each base consists of a number of buildings of different types, each serving a unique purpose. When your team is defeated (when your base is destroyed) it is assimilated by the surviving teams.

Army 21 is now live in early Alpha testing, for Windows 7 / DirectX 9 and higher. Indiegama plans to launch on Greenlight and Kickstarter later in 2015 after building up an initial player community. Pricing: free in Alpha, subsequent pricing TBD.
