Game Overview
Terraforming is both your economy and your weapon in this unusual real-time strategy epic, where whole landscapes shift under the pressure of expanding empires. Set across the surreal Chains of Worlds, Perimeter: Legate Edition follows rival human factions centuries after the Exodus, each pursuing a radically different future for humanity and the mysterious Psychosphere. You command Legates, military leaders who direct powerful Frames while settlements carve safe territory out of hostile ground. The mood is cerebral and alien rather than traditionally heroic, mixing grand ideological conflict with a constant struggle against destructive natural phenomena and the ravenous Scourge.
Matches revolve around claiming terrain, harvesting its energy, and reshaping the map to support your growing base. Engineers alter the land to create buildable zones, while protective energy barriers shield your territory from attacks and environmental threats; expanding carelessly can leave valuable infrastructure exposed. Rather than relying only on conventional unit production, your forces transform between specialized roles, letting a single formation adapt into combat, construction, or support forms as conditions change. Campaign missions place you in the perspectives of several factions over a long historical arc, while skirmishes and online multiplayer support large battles, including special maps built for more than four players.
Perimeter stands apart because its terrain is not decorative scenery: it is the central resource, the battlefield, and often the greatest danger in every mission. Its abstract architecture, organic sci-fi landscapes, and factional storytelling give it a flavor closer to a strange Soviet-era science-fiction novel than a standard base-building war game. Legate Edition brings the Emperor’s Testament expansion into the package, restores material closer to the original narrative, improves balance and visuals, adds widescreen and modern resolution support, and opens the door to custom mods. Fans of inventive RTS games such as Earth 2150 or Supreme Commander who want something less conventional should find plenty to admire, although newcomers need patience with its unusual systems and demanding map control.
