Battlefield 4 is suffering from a new exploit involving character classes. The glitch allows players to effectively combine two classes into one.
A video from EvilBeastLord shows exactly how the exploit works. First, the player changes the loadouts for two classes so that the first gadget slot is blank in one and the second gadget slot is blank with the other. Then wait until your next spawn. Select one of those two classes, and then quickly hit L1 and R1 (LB and RB on Xbox One or Xbox 360).
If you did it correctly, you'll spawn with gadgets from two different classes. Arguably the most potent gadget combo, featured by EvilBeastLord's video, is the Support class' Ammo Bag and a rocket or missile launcher from the Engineer class. This combination effectively gives you an unlimited supply of ammo for your launcher.
This isn't a game-breaking exploit. Ammo Bags regenerate missiles at a pretty slow rate if memory serves. Still, an Engineer sitting on a hill with an anti-air or anti-ground launcher and limitless ammunition is a big advantage in the battle. It's somewhat counter to the team spirit of the game, too.
"There is a reason why there are separate classes," EvilBeastLord said on the YouTube description for his video. "Because this game is a strategy game. You need to work with your team mates."
The bug isn't consistent. EvilBeastLord tried to use the bug with C4 equipped for Recon and Support classes and didn't get double the usual amount. The Recon class' MAV apparently doesn't work with the exploit either.
While the exploit isn't that disastrous, it's the latest in a string of headaches for the Battlefield 4 team. Bugs have plagued the game since its launch last fall. At one point, DICE had to pause development of BF4's DLC packs to focus on patches. It's shocking to see bugs like this still cropping up nine months after the game's release.
The team may have had to rush BF4 out the door to meet the launch dates for the Xbox One and PS4. They're apparently under less pressure with the next game in the series, Battlefield Hardline. DICE revealed last month that they're delaying Hardline's release to 2015. Stability was one of the major reasons that they wanted extra development time.
"We’re going to be using the extra time to continue to optimize the game for a stable launch. We have learned a lot from Battlefield 4, are continuing to learn from our Community Test Environment and will learn more from another Hardline beta. More time allows us to surface issues that the team can attempt to fix prior to launch."
