I'm looking to platinum this game, but to do so I'll need to get a trophy that requires 4 players to play past Infestation wave 9 (any map) without anyone dying. I heard you can simply start on wave 10, finish the wave, and still get the trophy, so it shouldn't take too much time or effort to get. The only problem is that this trophy requires 4 players, and with the servers being a ghost town, I came here to seek allies. :D
My PSN ID is Breadcrab. Let me know if you want to help get the trophy.
