introduction :

this game is a unique type of fighting games , mosty we have played games in which we fight with other players but in this game you have to support each other to win the different maps.

DDraceNetwork (DDNet) started out as a simple modification of Teeworlds, a 2D shooter. But in DDNet you don't fight against each other. Instead you work together with up to 64 people and fight your way through maps. You will see the best and worst in your team mates when they save you from certain death or leave you behind. We've developed DDNet for 6 years now and made it greater than ever!
