If you plan one getting the full 1000 in this game, you'll have to have some pretty dedicated boosters. The 2,500 kills achievement is pretty time consuming. You can get around 50 kills in a ten minute match which is 300 kills an hour. So according to my calculations if you go non-stop with at least four players, you'll get this achievement in around 8 hours. The other multiplayer achievements can come fast with boosting.
Minimum number of playthroughs needed: 1.2
(you have to play last level 2 more times on Hard and Insane at the very least.)
You can only get 50 kills in 10 minutes, if your killing all 3 of those people. So that is 8 hours PER PERSON
. Which means 32 hours
. My method takes 2 people, both getting 130 kills every 30 minutes. A grand total of 9.5 Hours
for both of you.
So the game takes about 14 Hours
to 1000 assuming you boost fast, and use the difficulty glitch at the end.
