I am trying to do it quickly since I can only really play on the weekends. So far I am at 127/250 kills. I found the French Lorraine 155mle to work well due to the oneshot ability of large caliber High Explosive, as well as the Swedish SAV with its very fast rate of fire. Sometimes I also use the PakPuma but with very mixed results. Here are some of my good results:
For me the Rerun Box ist interesting. Although I am probably just gonna get the dann Toldi out of it. I really do not want to get it from the box, so it will be very likely to drop. Murphys law and all.
Kills? It’s kills AND/OR assists. Which makes it actually very easy. Since it can be all one, all the other, or any combination. If you play a Ground game and make 6 kills and and get 4 assists, win or lose, that’s 10 added to the tally. It’s actually very relaxed and I prefer challenges like this.
