Over the festive period they released an LTM called ground game where ammo and materials where limited. I think you were given 20/20/30 materials and like 200 ammo max (dependant on the weapon). I seen a lot of hate towards it however me and my friends really enjoyed it, and i genuinely think it should be a permanent mode.
The way in which the game is played is completely different, it seemed to rely more on game sense. It relied on using natural cover and good positioning to gain an advantage over your opponents, it was less about pushing every team you see and more about securing high ground in the next zone and defending it and being able to use trees and out buildings during your rotations for cover (planes were also very uncommon, i think maybe 2 or 3 spawned per game).It had a couple of disadvantages, explosive weapons like quad launchers were extremely overpowered.
Your probably thinking that i am just a bot that doesn't know how to build, however i am a goo...
