Chivalry: Medieval Warfare is a PC exclusive first person combat sim with deadly combat where one hit can can take someone out, with both multiplayer and singleplayer.

i guess Chivalry isn't dead? or is it?

Looks Mount&Bladeish

It's about to get decapitated ether way 

Looks pretty promising if you ask me The issue is, that I still havent found a single game that manages to truly capture 1st person melee combat. There are plenty out there that are doing an OK job, but down to perfection? Nada. 3rd person on the other hand is in a much better situation

now that peaks my interest.

Is this the Half-Life 2 mod that is now made into a professional game?

War of Roses?

yup, now it's a UDK game
