An Extraction game is played over four different maps and lasts a total of 16 rounds and you will fight an array of enemies which include grunts, heavies, commandos and elites. To gain this achievement you MUST be in the pre-game lobby before the first round starts and you MUST stay in until the end of round 16. This achievement took about 2-4 hours for me and two others to complete.
- Find a good position and stay there. If you try running and gunning you won’t last very long as you are seriously outnumbered and overpowered.
- When running low on ammo go up to one of your partners and perform a partner reload. These are infinite and will restock your ammo and grenades.
- Balance your weapon sets. Don’t have four players with a sniper rifle, it just won’t work. I found the best load out is have two players with assault rifles/machine guns, have one player with a shotgun set and just have one player with a sniper kit.
- When heavy enemies appear split up. If you bunch up they will destroy you in no time at all and shooting them in the back is very effective. So spread out and also give him a few headshots. Grenades are also very good if you can throw them accurately.
