ArmA At War
Maybe this is a nice alternative for people who are interested in PvP/TvT in ArmA 3, but are not the biggest fans of game modes like King of the Hill, Exile etc. The origins of this game mode come from the Project Reality Mod for ArmA 3. Some of the developers decided to leave that project and they continued their work under a different name.
So ArmA At War is a framework made to offer TvT/PvP in ArmA 3, without going into the direction of other game modes I mentioned. The gamemode runs on vanilla, but the goal is also make this as compatible with mods as possible.
There is currently a testing-server online in germany. You can find the server information
here.
I will keep an eye on this and maybe try to play it when people are online. Might be something we could even keep an eye out for our own public server. Maybe we could do something like a TvT week or something in which we do TvT inside the unit and run this with our mods on the server if it is ready & stable.
