SDK tools mode problem

I’ve been able to run it fine. Checked and I’m able to use it still. Any specific error you’re getting?

No error messages. In library, after 2 clicks to launch the game, I can see “Running”, “Syncing”… and… no more messages. But game just can’t start in tools mode. Without "-tools’ in launch options, “everything” okay. I’m (Re) installing at this moment.

RIP Alien Swarm on 2nd acc, “Moving” this game to 1st one.

EDIT: Got it! There’s another command to put in launch options for Alien Swarm build 15727. Thanks anyways!

Updating. It’s not working. I think they removed this feature from AlienSwarm. YYXQxta.png1362×491

Fixed. Thanks GOD!
