Hello guys, i searched the forum and didn't see any mods like this.
So my idea is:
when the round or match begins the NUKE is launched(server-side or host, not for players in killstreaks)
and the timer start countdown,but,only after the time ends
[HTML]Team Deathmatch or Free for All
set scr_war_scorelimit "20000"
set scr_war_timelimit "20"less or more,time or scorelimit[/HTML]
the NUKE kill all players and the game ends(something like Nuke Town)

Features:a wellcome message,timer for nuke

Object:Modern Warfare 2
To be played on:FFA and TDM
