Exactly how?

Long did it take those of you with 1000/1000?
I can rent games for 5 days for 5 bucks and this is one I'm interested in for fun and that 1000. Just wondering if it is possible and if so how hard to beat the game 1000/1000 by myself?

I'm good at video games.

Edit : I'll clearly play co-op for the ones needed.

you cant get it by yourself. you have to have a buddy so you can swap co-op achievements. two days max is all it took me for 1000
