In the case of Interchange, Killa should be able to spawn just about anywhere. The garage, Oli, Idea, Powerstation, you name it. But the catch is he does not spawn right away. When he does spawn, an intercom should come up letting everyone on the map know where Killa is (for an example, it could say “Powerstation Breached” or something). This would force anyone who wants him dead to have to fight it out creating very engaging PVP encounters. PLUS it would mean no more bringing a Vepr Hunter to one tap killa, as you would need an actual loadout.

The random spawns is extra important otherwise people would just camp the middle area for 20 min.
