Shotgun

The shotgun is a frequently occurring weapon in the Tomb Raider series. It has appeared in every main Tomb Raider game up to date.

Tomb Raider-Tomb Raider Chronicles
The shotgun appears in all games of the original series. It offers massive damage, but severely short range. It needs to be reloaded after every shot, but offers massive firepower. The model in TR1 and 2 closely resembles a Mossberg 500, given the square ejection port on the side. The model in TRIII is a Franchi SPAS-12 with a shortened barrel, which was retextured in TR4 and TR5. However, the shotgun in the last two entries looks inaccurate, due to the seemingly absent pump.

The shotgun fires 6 pellets per shot with random spread applied. Each pellet deals 3 damage, with the exception of TR1's dealing 4, for a maximum of 18 damage per shot, or 24 in TR1. TR4 introduces wideshot shells as a second ammo type, which has double the spread, with the normal ammo having a narrower spread (around that of the pistols) than in previous games to compensate.

Tomb Raider: The Angel of Darkness
The shotgun in Angel of Darkness takes the form of the V-Packer, based on a Mossberg 500 Cruiser. It comes with 6-shell boxes (PAL version) or 25-pellet (NTSC-US version), having either standard or wideshot shells (the later of which were cut from the final game). It may have been intended to fire all 6 pellets in one shot, prompting a pump to reload like a shotgun should, but likely due to time restraints and rushed development, it remains firing single pellets at a time. Ammo is very common, particularly in the earlier stages of the game. However, it will become useless after Galleries Under Siege, since Lara will be stripped of all of her weapons by Kurtis.

Tomb Raider Legend
Lara can find shotguns from fallen enemies; it begins appearing in the second level, Peru - Return to Paraíso. It deals heavy damage at close range, usually killing regular enemies in one hit, but has limited ammo, and is not used much by enemies. It comes with a 5-round capacity, with a maximum of 25 shells. The model is based on a Mossberg 590 Mariner Cruiser.

Tomb Raider Anniversary
The shotgun returns to match its counterpart in the original. it has an 8-round tubular magazine, and a max ammo capacity of 40. It can be found as a Secret behind the second waterfall in The Lost Valley. If not obtained there, Lara will still take it from Larson after the Tomb of Qualopec. It can be reacquired in Natla's Mines after the fight with Larson.

Tomb Raider Underworld
Lara has access to a GN Tactical Shotgun as a selectable weapon in her inventory from the start of the game. Ammo is restocked only between levels. Depending on the difficulty, the given ammo capacity is between 42, 72 and 90 shells. It is more effective than other shotguns in the series, though it is still more powerful at long ranges. This model is based on the FN TPS.

Tomb Raider
Lara acquires a wartime trench shotgun, exposed to the elements in a chasm along the monastery. It can be upgraded to a Pump-Action Shotgun, and later a Combat Shotgun, when sufficient shotgun parts are found. Each new model offers additional upgrades. The shotgun has the added function of destroying wooden barriers.

Shotguns
Retooling the Tomb Raider 2013 version from a mere infantry commonplace projectile weapon into a genuine "incendiary weapon" (the United Nations has designated "dragon-breath" shotguns thusly) through the key "Incendiary Shells" upgrade indeed increases its deadliness, almost qualitatively, and militarily outclassed enemy combatants react accordingly.

Trivia

 * The shotgun, as it appeared in Tomb Raider and Tomb Raider II, featured in earlier versions of Tomb Raider III (such as the demo of it that came with Pandemonium) until its appearance was changed to what is in Tomb Raider III now.
 * In an earlier version of Tomb Raider: The Last Revelation, the shotgun in the inventory looks different to how it does in gameplay. In gameplay, it looks like the Tomb Raider III shotgun. The inventory one also appears to have a Flashlight on it. Perhaps Lara was to have used the shotgun as a light source as well as a weapon.
