the player begins the game with only two weapons: the "omniwrench 8000", a standard melee weapon with a variety of uses such as interacting with puzzles in the environment, and the bomb glove, a short-range grenade thrower. as missions are completed across the game's various planets, more weapons and gadgets become available, including the blaster, an automatic pistol; the pyrocitor, a flamethrower; and the suck cannon, a vacuum gun, which sucks up smaller enemies and converts them into projectiles. weapons are either found, or can be bought with bolts, the game's form of currency. the omniwrench remains the standard melee weapon for close combat, with its own button, as all other weapons assume the role of secondary weaponry and can only be equipped one at a time, though all weapons can be carried in the player's inventory.
