Working on a new concept for a Custom Arena. This will use TwinRvr, the only map that has bridges that you can destroy.
The objective will be to link your bases supply line from 3 bases away and across the river before someone has either set up ambush camps or destroyed your only route across. Once across the river you will have surrounded your enemy and by completing your supply line to the last base in the chain you will then have an operational vehicle base just on the outreaches of your enemies only access to his surrounded infantry bases.
There will be no field captures and no C47 aircraft. The barracks will all be destroyed except for your starting point. The downtime will equal the time that the arena will run on the server. Ressuply will be boosted to provide a reasonable amount of trips, that will make it challenging. No ordinance will be available for aircraft and hangar hardness should prevent any interruption in reinforcements other than direct confrontation from enemy ground units and of course strafing of the all important river crossings.
