Despite the seemingly lack of genuine care for the presentation of the PC version, the gameplay remains as fantastic as it has been in any other form. Without spoiling too much of the gameplay, you will often find yourself in large-scale battles fighting multiple enemies at once coming from every possible angle. In one area you can take shelter inside of a two-story building from a horde of enemies outside, and can push desks and bookshelves to block entry from doors and windows. Not to be thwarted, the enemy then raises ladders up to the second story, and if a zombie has a chainsaw it can cut right through the door like a power tool version of Jack Nicholson in The Shining.
The PC version of Resident Evil 4 does have some content not found in the original GCN version such as some additional costumes for Leon and Ashley as well as the Separate Ways scenario in which you play as the mysterious agent Ada Wong, which in and of itself is both entertaining and fills in even more of the back story. Not seen in any release prior to the PC version is the inclusion of two new weapons: a laser cannon and a gunpowder bowgun, and while neither of which make an appearance for quite a while, once you get them they are fun to play around with, although not a necessity.
It's not that the PC edition of Resident Evil 4 is a bad game. It’s just dated and sloppily ported. It’s hard to get past the lack of mouse support; a big reason to play a game like this on the PC is to use the mouse and keyboard and without that option the lure of the PC is lessened. In the end, it’s not a terrible deal for newbies at $19.99 but you expect more from such a high profile name like Resident Evil.
