Visually, this map is amazing. The displacement buildings make the map look incredible. In addition, Player Destruction is a really fun gamemode - it's just finite Team Deathmatch.
However, the UFO delivery is really finicky, and it's ridiculously hard to climb up there - you're just a sitting duck in the beam.
Again, this map looks amazing, plays amazing, but the UFO just ruins it for me.
I think that deathmatch in this game favors players who know what they're doing - and that people who aren't good at deathmatch wouldn't like to be tested on their ability for it. I think deathmatch-savvy players want something like WG to test their skills and have fun with (like matchmaking but more casual, but not as meaningless as hightower).
