G'day lads (or ladettes),
And today i have a new topic, which i hope to make a YouTube video out of it. It's the Top 5 GORIEST games in Video Game history. Any genre is included, including zombie games (obviously), across all platforms. No game is off limits, if there's gore in it, it's up for grabs. Feel free to leave some gameplay of the game in this topic, as it may feature in the video (you will be credited).
Good luck people,
Fearnzzz (JiffyNoodles)

This is the list of games that in the contention for goriest games so far, this list contains both votes from you guys and from the public of my school (This list will stay open for 3 more weeks, so get voting)

Good Luck!

Obviously not my gameplay video (it's a trailer), but you might want to consider looking at this game

mortal FUCKING kombat. does it need saying?

Just a heads up, the more a game is mentioned the better chance it has of making the No.1 spot (unless you're the person mentioning it repeatedly).

Manhunt 1 & 2, Postal 2, W@W (Duh, the game was known for its gore!), and Dead Space

- Postal 2

and Shadow Warrior:

(The original version was the goriest dos-game I've seen. Didn't know how much gore you could show with sprites.)
