This is an invasion map based on the Stargate: Sg1 television series. The map uses the invasion game mode to pit alien invaders coming through the gate against the human defenders of the Stargate Command.

This is a 3 staget invasion map which requires a custom game mode for intended play. The game progression should be as following:
Capture Hill -> Assault -> Steal the Core

The first phase of this map takes place on an offworld site, the objective of the human defenders here is to stop the attackers capturing the hill ( a DHD or dial home device) which will allow access through the teleporter ( stargate ). The Stargate has a turret and a sniper rifle spawn for defence with the attackers being given a plasma launcher and some additional ranged weapons.

Second Section of the map sees the defenders attempting to hold the Stargate within the SGC, the teleporter is one way so only attackers can come through. A turret and some barricades overlook the Stargate.

Make it out of the gate room, past the dialling room and up the corridor you will find the meeting room which overlooks the gate room and the bomb plant location for the assault phase. The walls blocking the tunnel at the plant location are gated objects which will be removed for the next phase.

Here is the plant location (note: gated obejcts removed to reveal open blast doors):

The fight then leads through the security room, up the evelvators, into the motor pool and to the exterior of the mountain complex. The goal of the attackers here is to capture the core being held by the defenders, both teams have access to vehicles and jetpacks for this phase. The defenders have at their disposal a rocket launcher for dealing with the enemy hogs and a rocket warthog.

If the attackers succeed in grabbing the core their final objective is to escort it back to the gate room winning the round.

Many thanks to PMS WildFire who helped to check for accuracy according to the television show and also to MyBoring Life who helped me with the spawning and finnishing touches.

Any feedback or suggestion to improve this map in terms of aesthetics or gameplay would be much appreciated.
