Tomb Raider: Underworld is an action-adventure video game that takes the player through a range of epic and unknown worlds. Players can explore ancient mysteries hidden within coastlines, jungles and frozen islands using Lara's upgraded inventory which includes an active sonar map, multi-purpose grapple and all-terrain hybrid motorbike. With a broad range of acrobatic abilities available to them, players must use objects in their environment to uncover new paths as they work their way through levels that are disguised as interactive environmental playgrounds. Combat options include the ability to pacify or kill enemies with the dual-target system and shoot with one hand while suspended with the other.
