Interloper is a real-time strategy game designed for Windows OS. The game is set in an online multiplayer environment, where players compete to claim domain instead of destroying their opponents. Matches in Interloper are fast-paced, taking only 5 minutes, and require players to predict their opponent's movements to corner them and claim the entire map.

Interloper is a distilled version of traditional RTS mechanics, providing a focused, stripped-down, and accessible strategy experience. The game features various difficulty levels that allow players to compete against AI or other players in online multiplayer mode. Additionally, Interloper has extensive single-player content that reveals the depth of the game. Players can also view replays of other players' matches and upload their own for others to see.
