I was playing with a friend of mine the other night and we always play pretty seriously. We don't win that often but usually finish top 10. We decided to do a complete 180 on our play style and decided to just look for quick weapons, then both got cars, heading straight on into action and trying to run people over. We were having so much fun and were pretty successful.
It's an amazing strategy in duos. Circle a building you know someone is in until they're forced to come out. They'll duck the first car and then run away, leaving the second car a clear shot at the guy. We were getting so many kills just running people over, I never thought it would be such a strong strategy. One game the circle was on the southern island so we landed just north of it, found assault rifles, and both went for the bridge in our own cars. There was a battle there before and we set up a road block with all the cars on the bridge. We both ended up with 8 kills each, mostly on the bridge. We just stayed in our cars the rest of the game but got killed when one of us landed a bit sideways and turned into a tree with an enemy behind it. I ended up trying to avenge him and killed the guy he got killed by but quickly got killed by someone else almost immediately.
I continued that strategy in solos and just won my second solos game today! I literally looted level 1 helmet, level 1 vest, AKM with 60 rounds, and a double barrel shotgun. I got in the first car I found and just drove around looking for people. I didn't even see the first three kills I got, I only knew they were there after they shot at me. I got the last four kills with my UAZ because it ended in the wheat field near Yosnaya Polana and I just drove over people when I saw them prone in the grass. I swear, people don't seem to know how to deal with cars and if you play very aggressively, you can get some easy kills. Just remember you always exit a car on the left side so if you are going to exit, make sure to have the car between you and your enemy.
You'll find plenty of ammo and first aid from the people you kill so just look for an AR and car, then just get going to kill people. My win was with 8 kills, 4 or 5 of them were just running people over.
