"Run, jump and fly across massive boundless battlefields as you compete against fellow warriors" is the official catchcry from this game and it could not describe it better. Starsiege: Tribes puts the player in huge open environments wielding a fine arsonal of weapons - delivering end action packed fun. With such a fine-as original game concept the mods created really do stray from the typical First Person Shooter gameplay style and MUST be played, as they no doubt will prove brilliant!
