I'd like to know how to detect when two players are killed by 1 grenade.
I'm not sure if deathmsg defines the killer properly when it's done by grenade, so:
1. Is the killer in DeathMsg index of player who actually killed someone with grenade? If so, is the grenade's string "hegren", as it is for all other weapons?
2. How do I detect if it was a double kill?
For the second point, I think the gametime for both the kills should be the same, but I'm not sure.
