Spear Gun

The Spear Gun is a recurring weapon in the Tomb Raider series. It appears in games that have multiple aquatic levels.

Original Timeline
Tomb Raider II - Tomb Raider III The Harpoon Gun appears as the "Harpoon Gun" is the weakest weapon in both Tomb Raider II and Tomb Raider III. It's useless out of the water, and even inside it is a really bad gun. Usually it's best to just avoid enemies when underwater, because if the player uses this weapon, inevitably it will be just a waste of health and oxygen. There are plentiful of ammo for it, but is recommended to just leave it in the inventory.

Firepower: 2/10

Firing rate: Average, but after four shots it has to be reloaded.

Tomb Raider Underworld
The Spear Gun returns for the first time since Tomb Raider III. It is more powerful and reloads faster, using a pump action than the previous spear guns in the series.

However, Lara's Pistols and Mjolnir can both be used underwater, which are far more viable options, since they can shoot faster and are more powerful respective.

Trivia

 * After beating the game once on both games and unlocking infinite ammo, the Harpoon Gun will change to an even smaller clip size of only one shot, and because of that, it's recommended again to just leave it in the inventory.
