The registration for the 1vs1 tournament on Contra 007 is open. Games will take place in the network Hamachi (info here). There will be 2 levels of playing: PRO and amateurs. Register for the tournament here, and the rules are here. In PRO category factions are chosen randomly, and in amateurs player is given a choice. Maps can be downloaded from here.
P.S.: I suggest all players to get Skype, it's easier for you to find opponents.
