 is a set-piece storyline task that is assigned in the S.T.A.L.K.E.R.: Lost Alpha standalone mod.

"Hey man, sorry for the delay, car was being a bitch. I hope I'm not too late to the party, 'cause I want a piece of 'em too! What's the situation?"

"The mercs that murdered your friends and stole the Crystal artifact are in the warehouses up ahead. An entire garrison unit from the looks of it."

- Marked One

"That won't be easy. As I see it, we need to get past the snipers in the towers and several patrols of mercs. I hear that a blowout is expected soon, so this should help create confusion among them. Follow me in, and I'll personally find the bastard who did this! As payment, I'll let you keep the artifact in question. It doesn't matter to me now that the gang is dead... You take out the first sniper at the base entrance, and then we will storm in! Have some tact - use your sniper rifle and keep the noise level low."
