Hello Demon Hill fellows , so maybe you will think , wtf is this title o_o

But here it is , I made this one to show you guys a way to have the valve gift grab 2011 , in 2012 !


I've found this vids , it's very easy .

You just have to follow the instructions and install mutations mod (which it's veryyyy funny :D )

After installed just create a versus co-op lobby ,play with BOT or your friends and don't FORGET to play in local server .

And yeah , after reading the comments i've see that it's nott working in 2012 .
To make it you just have to change date in your PC to 2011!

So here it is : Back to the future my friends :D

Boom Headshot! – Only headshots will kill zombies, but each zombie goes down in one hit. Special infected also need to be killed with headshots.

Ultra Realism – Realism mode but even harder. Death is permanent for the entire campaign. Basically Realism and Iron Man mode combined.

Last Man on Earth – This is a mutation of single player mode. You will play through the campaigns alone without any assistance from computer controlled characters. Only special infected spawn, and reaching incap means death.

The Last Samurai – Another mutation of single player mode. You will play through the campaigns alone armed with only a katana, facing wave after wave of normal zombies.

The names of these modes and final gameplay parameters are not final and subject to change, and of course more mutations will be made as time goes on, however this is a pretty interesting list to start with. I’ll see you on the versus survival floor!
