In Kleiners Adventures, you will start in the garage by your car as Dr.Kleiner in the year 2002 while Xen's portal storms come into White Mesa just as you arrive to work. You find military, scientists, and security guards all dead and you have to find your way to safety, but some soldiers still stand. You might find a gun on your way exploring the destroyed facility. The military is NOT your enemy! You will fight through aliens alongside with the military through buildings, outdoor environments, and all the way to the other side of White Mesa to regroup with a group of guards, and scientists that wernt evacuated with everyone else. That is your way out of White Mesa. (You cant just leave from the garage because the door gets busted)
