While gameplay from Fallout 3 was retained for Fallout: New Vegas, Obsidian Entertainment worked upon providing the game with improvements upon existing elements while introducing some old and new features to the series. Some of the improvements and new features included: Combat is improved upon, with the V.A.T.S. system being updated with several new V.A.T.S.-specific attacks, and a number of kill animations being made for several of the game's melee weapons. Players can use the iron sights on firearms in the game, with the exception of certain larger guns and some energy weapons. The third-person perspective in the game was redesigned to be more "over the shoulder" than it had been in Fallout 3. The Character Creation section of the game was refined to take less time than Fallout 3, with players able to skip the tutorials and proceed across the Wasteland once their character is set up.
