The best and only true Co-op mod for Half-Life 2's. It is little bit buggy, but aside of that having friend next to you bugs dosen't really matter. You are more likely to laugh to them than raging over them. I highly recommend this to people who are reaching together with friend for fun co-op experience that is of course Synergy.
