i had the same thing happen to me a while back, except it was a teammate's grenade and i spawned as soon as it blew up (i had to slow it down to 20% to really see it, it was quite cinematic actually)
Oh well at least it's legit. Getting spawn killed by the glitch where a grenade goes off close to your buddy even though you spawn somewhere else on the map is the worst.
I'd say the worst version of the spawn kill is directly tied with the stupid programming of Revenge. It also shows why Revenge users are not team players whatsoever:
- Marked Man uses Revenge
- Marked Man gets killed
- Marked Man's own Revenge grenade kills Marked Man on Spawn
