Dynamite

The Dynamite is an explosive made of nitroglycerin, sorbents and stabilizers.

Tomb Raider (1996)
Dynamite is an item that appeared in earlier versions of Tomb Raider but is not present in the final version. The dynamite was first replaced with a Grenade, but it too was later removed. Dynamite would have been used to blow up secret doors and as a weapon.

Tomb Raider: The Last Revelation
Dynamite was again planned to be added into the game in the form of combination puzzle, with explosive and detonator. According to the design documents the dynamite would of been used in the Giza levels in Western Cemeteries to blast open a way into the Queen Mercerankh's tomb. The dynamite didn't make it into the final game.

Tomb Raider (Game Boy Color)
The dynamite is used to blow up walls and floors. Since the dynamite can be placed anywhere on the map, it can be utilized to kill enemies. It's a limited use item, but it respawns at the specified location after being used (spawn location must be off screen). The fuse is short, so one must hurry and move away from the dynamite once it is placed.

Tomb Raider: Curse of the Sword
The dynamite works exactly as in the previous game, but now a single pickup gives three dynamites.

Tomb Raider: The Osiris Codex
Dynamite is found in the game, as an object that can be picked up and placed on walls to blow open pathways. The dynamite will not respawn like in GameBoy games, since it can only used in preset locations.

Tomb Raider: Quest for Cinnabar
Dynamite is used similarly to the previous game.

Tomb Raider: Anniversary (Mobile)
Dynamite makes its appearance in the 2D mobile version of Tomb Raider: Anniversary which is built in the same engine as the mobile trilogy. The dynamite is used the same way as it was in the mobile trilogy games.

Tomb Raider (2013)
Dynamite appears in the Multiplayer under explosives. It can be used after level 37. A pack of dynamite with a remote detonator can be detonated by pressing middle mouse button after it's been placed. Dynamite can also be detonated with weapons fire.
