Ever wanted to Hunt Down the Freeman™ together with your friends? Well you can - and it's kinda broken!

It's pretty simple to start up your HDTF coop server, you just gotta forward the HL2 ports
(TCP: 27015-27030 UDP: 27000-27031)
Then, start up HDTF, open the console and type in maxplayers (put any number of players here), then start a map and boom! you're hosting a HDTF coop server!
Now any player you want can join the server by typing connect (server IP) into the console!

Though - be warned, as the game was not made with multiplayer in mind, the game's pretty unstable and might crash at certain points!

Have fun!

Here's a list of issues i encountered while playing HDTF coop:
- Every player is the default broken player model from hl2, which means it has no animations, no nothing lol
- Friendly fire is on by default and can't be turned off
- No blood particles show for the host for some reason
- Cutscenes don't play and no level transitions, so you'll have to load the next map manually by typing in changelevel (mapname) in the console
- Other players will not get the weapon loadout at the start of the levels, so they will have to type in impulse 101 into the console to get weapons
