Metro 2033 is a very special project that has for goal to give you another angle of view on Metro Licence.
M33HH will have its gameplay reviewed, because of the tunnels that can not allow players to use tanks, planes and others.
Main forces will be infantry, but obviously some tanks or vehicles will be available, according to the vehicles of original M33.
About the multiplayer side, the players will have to fight in tunnels with a station "base" and will have to take ressources from anothers neutral stations, to defeat adversary.
Conquer the stations, like communists, nazis or others in the original game, will be essential.
Darkones will be included in the mod too.
Do not hesitate to help me if you are interested :)
