"Starsiege" received "generally favorable reviews" according to the review aggregation website GameRankings. IGN highlighted the well presented package and cutscenes, graphically impressive (whilst sparse) landscapes, intuitive controls and the longevity of the multiplayer mode. The minimal sound effects were criticised, with muddled voice-overs, and some of human HERC models were felt to be a bit bland and generic. GameSpot said, "Starsiege brings new life to a genre otherwise devoid of it, even if it doesn't really succeed in elevating robot sims out of their long-term rut".
