God, tried one of the story missions on hard, it was brutal when the enemies came at you in waves with very few places to hide... Had 6 eyeball things after me at one point. Each quite a few levels higher than me. Took me and my mate so many tries to complete that level.
Also is it just me or are way more people rocking titans? In the alpha I remember there being tonnes of hunters, quite a few warlocks but very few titans. I'm personally using this class for the first time as I was rocking warlock for the entire alpha. Gotta say, loving the melee and health on this class so much! Hating the super though. It's weird as it has to be on the ground and the range is terrible. Much prefer the nova bomb. So much better. The grenades are pretty awesome though. Especially the flash bang.
Are we getting any more areas to explore? Other than the promise of more multi maps, I don't see this as being that different to the alpha. There's a few more story missions, and the beta logo is bigger and annoyingly more prominent sure, but other that I don't really see much difference.
