Unlocking an entire kit in Battlefield 3 may take up to, if not more than, a hundred hours according to Senior Gameplay Designer Alan Kertz, who tweeted in response to a question on the average time it takes to complete a kit.
"If you unlock every weapon, every gadget, and every unlock for every weapon"¦ something like 100 hours," tweeted Kertz.
It looks like Battlefield 3 is pacing itself out for the long run with the new weapons customization and unlock system. The game is out October 25 on PC, PS3 and Xbox 360 complete with a single player campaign, a separate co-op mode and of course online multiplayer, all brought together with the new community hub Battlelog.
