Urban in general sucks. They really should have just gone with Noctus instead. All the rubble makes it difficult to dodge fire in a tank and almost impossible for a team to use multiple tanks. This is easily the worst of the firefight maps by a long shot. They need to scrap it and just use the full map.
The Phaeton round is horrid as the only place to really hide is the garage because of how small the map is. It is doable but the Phaeton round would have been so much better on noctus with the monument in the middle.
The warden 5th round is absolutely absurd. You have to kill 4 solider bosses on top of the armor which takes a little over a minute. Then they spawn about 20 knights in front of the main base. Factor in what I said about how bad the map is for vehicles and you have a time consuming battle. Then, when you finally come across the wardens, they are in the back of the base in positions that can only be hit by one vehicle at a time if you are lucky. Otherwise they are hiding in the hanger and you have to somehow use small arms to kill 2 beefed up wardens and the mythic one. All of this in 5 minutes on a horribly designed map is just awful.
The defend round is pretty stupid as well. It is the 2nd round where most people are Req 2-4. The prometheans spawn at the bottom of the hill in large numbers while the players have to spawn all the way back at the garage after 15 seconds. Trying to stop charging knights, who have scattershots, with only ARs and maybe BRs is so absurdly tough.
The spawning on this map is awful. Your only two vehicle spawn points are either the garage where you will be unloaded on instantly by phaetons, wraiths, banshees, etc or in the main base along side a bunch of enemies who also can shoot you as your vehicle rolls out. Player spawns on some of the rounds put you so far from the objective.
Overall I’d give it a 3/10 only because the covenant rounds are kind of fun.
