You and Leon got separated awhile ago. You two were on a mission in some large cave of a forest in the mountains of Russia. Neither of you had the connection to call each other over the comms, so you were stuck on your own.

After some monsters and something like zombies attacking you, and some weird puzzles, you cane to an exit of the cave. You could leave. Or you could go back for Leon.

Obviously, you weren't leaving him behind.

So you went back. It didn't take too long to hear grunts echoing through the cave. You ran towards them and ended up on a much higher ledge, conveniently next to a rifle, over a view of where Leon is below. You going to save him?
