You gotta record and throw on some WWE sound effects
I have found that this might a great battle, but it will be against each other, and the player just stands and takes target practice at either machine. It turns into Fnix against Soviet.
I would definitely would like to see if they are actually will fight each other, until one is left the victor.
This can take a long long time and probably is absolutely boring.
I even donβt know if the vulture will start its phases with the beacons and the turrets and lynx support, if it just fights another machine.
I thought that after the last update the tyrants/rivals should always select the player as the highest priority target. 
Yes, I wondered if the Reaper just would keep targeting the Firebird or would also take out the dropped enemies and Gas-pods and turrets, to get the Firebird to drop its shield., Same goes for the other way around to get the shield down of the Reaper.
I shoot at the reaper when itβs shields are down and the vulture when they are up. I used the south coast glitch to spawn them both in the arena. It was fun to watch. The runners of the reaper will attack the vulture, as will any fnix around. Lynx also will attack any of the fnix machines. You can run amongst them with a KVM 59 level 6 and watch the sparks jump. If you are lucky one machine may notice you.
