First thing you need are HL2 EP2 (because there are some hunters) and gm_oceanskydive_v4 map (http://www.garrysmod.org/downloads/?a=view&id=53962).
Parachute is not included!
Your mission is land to the island with resistance forces, kill all combines and kill Breen. This is my first try, don't be angry on me!
