Perimeter: Emperor's Testament is a standalone follow-up to K-D Lab's real-time strategy game Perimeter. It picks up where the first game's plot left off, with a large new single-player campaign, keeping the same core ideas: shield-protected bases, territory you reshape with terraforming, and units that can change form during battle.
Besides the campaign, it supports multiplayer matches against other players. It plays at a measured strategy pace that rewards planning over fast clicking. It is a good fit for players who finished the first Perimeter and want more of its story, or for RTS fans curious about an older and unusual take on the genre.
