Tomb Raider (2013)
There are miscellaneous Enemies that throw bottles filled with burnable liquid at Lara. Unlike Dynamite sticks - which can be shot out of the air - Lara can only evade these, or else they will burst open on impact with the ground and seriously injure her.
Molotov Cocktails are mainly used to draw Lara out of hiding so she can be shot by attacking Solarii after she left her cover.

Molotov Cocktails are also a possibility to burn certain cloth covered barriers or even the Posters of the Difference of Opinion Challenge, as Lara has not yet found the Oil Flask she needs for crafting Fire Arrows at this point in the story.
