And yes, I know what some of you are immediately, thinking, "Thank God" and "Where can I get this?". Well, we'll come on to the where, but first let me tell you about the why.
The addition of Mr. X to the remake, also known as T-00, has not been popular with some fans of the game, given his tendency to randomly appear and cause grief to the exploring player. Now you'll be able to explore the world without fear, as the mod completely removes him from the game.
Happily, it does so without causing any other side effects as far as we can tell, there's no broken cutscenes, character events or anything like that, so if you simply would rather he wasn't there, this mod does a pretty spot on job of making that happen. The only real jankiness is when it comes time for him to lift up the helicopter, but this seems to happen magically by itself. So if you can overlook this one minor detail, it's a mod worth installing.
Mr. X has been one of my personal bug bares of the remake, seeing as he just appears to absorb ammo, and the only effective strategy I've had is to just run the other way hide. Normally running to the main hall has been enough to loose him, but it's nice to be able to play through without fear of him appearing.
Now, enough of the why, the where. The mod's available now from Nexus, so head over and install it now.
