Members - Ground Complex mod for Half-Life 2

You have been sent alone, to a warm desert planet for a commando mission of high risk. Your goal, as an elite soldier, is to infiltrate the abandoned human complex to perform vital maintenance tasks and to recover precious scientific research facility data. From the warm desert to the depths of the complex, you will blow up everything that blocks your way, like doors or walls, but mostly aliens. You will then be extracted from the planet by a space ship !
