I cant exactly say anything too informative as I dont know duels super indepth but from the various matches ive had on this map it seems to be a fun one. The only thing I see being offputting especially for tdm would be that the spawns are all very close together and due to the pseudo-rng of doom spawning you will spawn very often in a position where your opponent(s) can just spawnfrag you. no need for the bfg really unless you cant aim with the ssg. Other than that its an insteresting enough concept that it's worth playing for a while, dont know about actual replayability value tho...
