We've been asked numerous times now if Admin Mod works with Counter-Strike

ource and whether/when we will make it work if it doesn't. Answers below:
No, Admin Mod does not work with CS

ource. It cannot, because the HL2 engine, that CS

is based on, too, is different from the old HL engine. You cannot simply push Metamod/Admin Mod on it and hope for it to work.
Whether we will create Admin Mod for the HL2 engine depends on demand. If nobody would use it there's no sense in wasting the time. If there is demand for Admin Mod on the HL2 engine (as the fact that we are being asked about it hints out) we will certainly look into porting Admin Mod to the new engine.
When that is going to happen cannot be answered by me at this time. Admin Mod depends on two things to happen before it can be ported to the HL2 engine. First, Valve needs to release the SDK for the HL2 engine. The SDK (Software Development Kit) defines the interface to the engine that all MODs and addons use to talk to the engine. Without it there is no interfacing with the engine (at least not in any sane way). Second, Metamod needs to be available for the HL2 engine since Admin Mod is a Metamod plugin. Right now nobody knows when either of those will happen. But don't expect anything before HL2 has been released.
