well as you are meant to go into the freezer and find a thermal scope, i didn't as i never knew you had to find one.
anyway after i aquired the freezer card from the operating room i heard a crash, and soon forth revealing a towering nemesis like figure called a 'regenerator', anyway after pounding him with bullets and blowing a few limbs off him i thought ha! he's dead, only to be awed at the fact that he then got up and continued towards me, anyway i then remembered the part of i think Luis' diary where he talks about the regenerators and how their metabolic rate was incredibly fast, as he then states that you can only kill them by finding the parasites on them using thermal imaging. I am quite far in the game after the castle and on the island inside the 'laboratory' as i call it with all the experiments in it and so forth.
Hey,well you see i bought the game for the Wii a few weeks ago and really got into it, being the unusual fact that i never really liked any resident evil games previously.
