Batman: Gotham Knights

You decide to hop in the Batboat and sneak up on the island. Landing at an empty beach, you ready yourself for anything and begin to trek towards the only civilization on the island, a communications tower at the top of a mountain.

Going through the forest isn't usually your thing, but it's the only way to get to your destination. You stealthily make your way through the trees and finally to the installation, where two armed guards stand outside. They are large, bald, and they wear red tunics. You recognize them as servants of Ra's Al Ghul, the Demon's Head.

This must be the "Head" Two-Face and Croc were referring to, you think.

You decide you need to get inside. If Ra's has Nightwing, then it won't be long before he does something drastic to get your attention.

But now... how are you going to get inside?
