Maybe add a killcam and a Final killcam and add a choice to save the Final Killcam.

The final killcam should show a first person perspective of the player who got last kill and it show the usernames of the ones in the background on top of their characters, and show the username of who got the last killcam.

Incentive

I hate to burst your bubble, but this game isn't part of the Call of Duty franchise. Killcams are just obtrusive, pointless, and downright annoying. All killcams really do is bloat someone's ego.
