The Lava Gun is a Megacorp Weapon in the game Ratchet & Clank: Going Commando. It is a spiritual successor to the Pyrocitor from Ratchet & Clank, but there are key differences. The most obvious one is that the Lava Gun shoots lava as opposed to fire, which does much more damage, setting enemies on fire. The Lava is shot out in a thin stream that can be twirled around like string, meaning this weapon can potentially cover a surprising amount of ground. Indeed, twirling Ratchet in circles while the Lava Gun is equipped is one of the best ways to deal with being surrounded by enemies, as the lava will form a sort of protective barrier around him.
One tricky aspect to the Lava Gun is that the gun still fires for a little bit after the player lets go of the Fire button. This can be a problem if the player would want to conserve ammo.
Up Your Arsenal
In Ratchet's third adventure, the weapon makes a return appearance as one of the weapons for sale by Slim Cognito on Planet Aquatos, although instead of upgrading into the Meteor Gun, Slim's version upgrades into the Liquid Nitrogen Gun. In addition to returning in the Single Player mode of Ratchet & Clank: Up Your Arsenal, the Lava Gun also appears in the Multiplayer mode too. Here, the strings of lava can be hard to avoid on the ground when the wielder is flipping from side to side (or just walking forwards), but the relative weakness of the lava give opponents a chance. The time it takes to kill an enemy with the Lava Gun is it's most significant flaw, however this is remedied in the upgraded version, which can kill in two hits. It's best used against opponents wielding a Blitz Gun due to the range and consistent damage level.
