I have spent the whole ~4 months trying to beat 3500 kills RS, the old world record. Finally did it! The whole struggle took 510 mins with 5 attempts.
Loadout used: Arc Shotgun, Stratagem Priority, and x4 Thunderer Barrage
Why Arc Shotgun?
Arc Shotgun’s charge is very fast and deals extremely huge damage to everything besides Warlords. But the main reasons I chose to pick Arc Shotgun is that I didn’t need ammo stratagem and it can shoot through all kinds of walls.
Why Stratagem Priority and Thunderer Barrage?
Thunderer Barrage was used to block all paths to me, I have isolated myself from all kinds of enemies and used Arc Shotgun to kill enemies via the neutral cover. Stratagem Priority helped to keep the Thunderer always ready.
Why did you play SOLO?
I have got a great huge and easy map for the 10k kills, the screen is very important. I decided that It will be a lot easier when I have the full screen for myself.
The run took around ~8 hours without failed attempts. It took around ~10 hours with all attemps.
