Not gonna lie, i loved Shipment for the easy 50+ kill count. When i played OG shipment, (this new one isn’t as good as the OG) it was very high kill counts: 60+ for top of the board, 30+ average. Which is the best way to progress weapons ranks. Then switch over to that other map I’m blanking on, to progress the specific kill type counters like crouched kills or longshots or mounted. 2 months of that and double weapon xps, would get you the final weapon camo.
Haven’t played CoD in a year though because i realized that’s all i wanted to play to unlock better stuff for weapons. Not even to play other maps or gametypes for those new weapons.
I would also recommend Hell Let Loose. We recently had a game night with about 6 friends who all come from call of duty style, faster paced games. All of them mentioned how slow it felt and half of them were able to adjust to the new style and did pretty good. I would compare it to Battlefield but in a hardcore mode with less destructable environments.
