C.) Kill the truck driver and disguise yourself as him, giving yourself easier access.
______________________________________
Slowly and cautiously you advance on the truck, which is stopped at a checkpoint, wondering where the guards are to let him in. A swift knock to the door and you bolt behind the truck, and you watch as the driver comes out, scratching their head in confusion. Sneaking behind him with a fiber wire, you wrap it around his neck and start strangling the life outta him. The mMan struggles and tries to scream, but to no avail.
Once he's dealt with, you slip on his uniform and I.D. and hide his body. You get back in the truck, and the lazy guard finally comes around to doing his job. He asks for your I.D. in Russian, and you quickly oblige, and after a few seconds, the guards seems satisfied and swipes you through the checkpoint. You drive the truck all the way to it's destination... the end of the compound near the entrance to the dam. The dam itself has multiple towers that lead inside the dam, and there's what appears to be a bunker of some sort on the low side of the dam
Now What?
A.) investigate the towers to see what's inside
B.) Avoid the towers, and find a way to the bunker
