Did you change the UI/HUD for the PC version of the game?
We made quite a number of significant changes to UI / HUD for the PC version of the game. The decision was made early on not to support controllers at all in order to ensure that we got the mouse and keyboard control absolutely right. This of course required a redesign of large parts of the UI and the player HUD. For example, we removed the Weapons and Plasmid Selection Radials in favor of a custom created Weapons Selection Strip which more accurately reflects the keyboard layout.
