Due to an error in Battlefield 4 you can now combine two classes, take the benefits of both and use them in the game. The error is confirmed to work for Xbox One players and it is possible to work for PC too.
It has been discovered by Battlefield 4 Central and they said that “All that’s required for the glitch to work is to pick a class, and select one gadget while leaving the other slot open. Then for the next class, do the same but in reverse. When spawning, hit the R1 and L1 buttons (on the Xbox, hit the R buttons), and you will now spawn with a combined class.”
Well, it took some time for the glitch to be discovered, but let’s hope it will be fixed.
