Grand Theft Auto 4 (GTA 4) Discussion
To get the achievement you need to do it on ranked. But from party mode you can only do it on unranked.
The only way to get friends into the same co-op game is to just enter new games until you're both in the same one. It's doable for 2 people but pretty much impossible for 4.
If you can find some ppl that know what they're doing and get your plan and do everything smoothly, it should be fine. It's not too hard.
