Geez, Planetside 2 really drops the player into the thick of things without explaining a lick of what is going on.
I played for an hour or so last night and it's obvious that I should have spent some time watching some of the suggested "How To" videos because I was completely mystified for all but the last five minutes.
As an engineer class, some of the "skills" I honed from Battlefield: Bad Company 2 I was at least able to help out by repairing tanks, but since the battle rages far and wide I felt a little inadequate, particularly because I'd sprint out into the open and be blown to smithereens and have no idea why.
