That RE 1.5 thing, is it a mod? cause I dunno, it just looks too jumbled to me, parts of it look like 1 parts like 2, some 3 and some of it like code Veronica. Besides that, the zombies looked harder to kill than ever, and those zombies at the end (in the lab that was destroyed in RE2) move way too fast, like crimson heads from the remake.
All in all it was a nice idea, but I'm pretty sure it's just a mod.
