Mass Effect 2

Save the galaxy again from the Reapers and be an asshole or an angel while doing it. Originally released for the PC and Xbox 360 in 2010, it got a PlayStation 3 port in 2011.

Cut Achievement/Trophy
An achievement called Sky High, which required you to lift 25 enemies with biotic powers off the ground, was in the game before eventually being removed from the final release for unknown reasons. It was eventually reused for Mass Effect 3 with different requirements (the difference being the number of enemies) and a different achievement image.

Cut Features/Gameplay Elements
Mass Effect 2 originally had a combat mode similar to Mass Effect, where guns had unlimited ammo and you had to wait a few seconds before firing again if they overheated. In the finished product, guns work as if they do not have unlimited ammo, and for all intents and purposes, the thermal clips the player can pick up serve as ammo clips, much like a standard FPS.

However, the code left over from when the combat system was similar to Mass Effect still exists in the game, and modifications to the Coalesced.ini can re-implement the code to a degree in the PC version.

This enables some guns (not all) to "regenerate" ammo, though picking up thermal clips will still work as intended for the most part.
