The Phase Gate is the Frontiersmen teleportation structure created by Marine Commander. Marines or MACs are required to assemble the unbuilt structure and Power Node nearby.

When powered, the teleportation system becomes active once two or more Phase Gates are built and powered at anywhere on the map. Marines can move through the portal to instantly travel to another Phase Gate. However, robotic units such as the MAC, ARC, and Exosuit cannot phase through.

Marines will be teleported in a sequence of Phase Gates constructed, from the oldest to newest. The Commander can recycle Phase Gates or reverse the direction of travel as needed.

Tactical Summary - Phase Gate

  • Phase Gates are a key component towards gaining map control.
  • Phase Gates allow Frontiersmen to quickly traverse the map and defend sudden rushes by Kharaa
  • Robotic technology such as MACs and ARCs cannot be phased through a gate.
  • Phase Gates and an Armory and an Observatory are good compositions for a forward base in-between Tech Point rooms or known Hives
  • When a Phase Gate is being attacked a good strategy is to drop Med packs at the entrance so your marines won't sustain too much damage when exiting.
  • Phase Gates are typically the first target in a rush, if a phase is being attacked and your whole team is away from your main base expect to be hit with a base rush.
  • Aliens will attempt to force a Beacon in order to push a well-defended Phase Gate or advantageous forward position, try keeping 1-2 marines back to prevent this issue or build Turrets.


Teleport Marine

Teleport Marine
Instantly teleports a Marine to the next active Phase Gate. Each player has a small delay before phasing again.
Delay 2 seconds
Targets Marine
Requires Nearby Active Power Node, 2 or more Phase Gates

Additional Tips

  • The Phase Gate is vital for bringing reinforcements to a contested area.
  • Kharaa lifeforms will often target Phase Gates in Marine-held territory as the first priority. Without the Phase Gate, reinforcements cannot return to the area quickly.
  • Phase Gate positioning as a Marine Commander:
    • try to place the Phase Gate where it can be covered from all entrances of a room.
    • try not to place Phase Gates against a wall; when the Aliens surround a Phase Gate any Marines phasing through will be trapped (against a wall and the lifeforms). This is referred to as a "meat grinder". Any phasing Marine is likely to be killed instantly.
    • When placing Phase Gates, position it where Gorges must become exposed to use Bile Bomb.
      • For this reason, around a corner is not advised because Bile Bomb explodes on impact, causing splash damage to nearby Frontiersmen units and structures.
      • For the same reason, placing a Phase Gate near a high ventilation shaft is also ill-advised.
