Me personally i grappendixed into the top window, nailer the guards and target, jump down, bunnyhop towards the other targets room, nailer opposition and the target then bhop tf outta there, not the fastest but easy s rank
abominator at spawn, nailer window and target, change abominator and enter window, go down into stairs, abominator to cancel fall damage, bhop to other target then kill and bhop to exit
