The software development kit for Counter-Strike: Global Offensive is scheduled to launch three months after the game itself, which is a lot like saying it'll drop "as the crow flies," since CS: GO doesn't technically have a release date yet. The SDK will allow players to mod and create their own maps, and is in development by Valve veteran Mike Durand.

The kit will include a few maps from Counter-Strike 1.6 that didn't make it into Counter-Strike: Source, Valve's Gabe Newell announced on the podcast Seven Day Cooldown. Newell said Valve has successfully integrated both titles into CS: GO, "unless the beta testers are blowing smoke up our ass."
