The Infantry Portal (also called the 'IP') is the Frontiersmen respawn structure created by the Marine Commander.

At the start of a round Marines will have one Infantry Portal if they have less than nine Players. If a ninth Player Joins a second Infantry Portal will automatically spawn.


At each round start, a completed Infantry Portal will be placed near the Command Station. If the number of players in the team exceeds 8, the secondary portal will automatically be placed (even if the 9th marine joins during the round). Any additional Infantry Portals must be built by the Commander in range of a Command Station.

When powered, the Infantry Portal will allow a Marine to respawn after a short materialization process. If the number of dead players exceed the number of Infantry Portals, Marines will queue for respawn. The Commander can set the rally point of an Infantry Portal to automatically issue a move order waypoint to newly respawned Marines.

Each additional Infantry Portal allows an additional Marine to respawn simultaneously. When the Distress Beacon from an Observatory is triggered, materialization time is bypassed and all respawning Marines spawn instantly.

Tactical Summary - Infantry Portal

  • Marine teams of 8 players or fewer start with 1 IP, larger teams with 2.
  • Infantry portals are attractive targets for alien rushes, especially in early game.
  • Before pushing a hive, the Marine Commander might want to increase the number of IPs to speed up the respawning.

Triggered Abilities


Recycle buildmenu
Recycles the structure over time and refunds resources based on initial cost and current Health. Recycle can be canceled by Marine Commander or by destroying the structure.
TSA Frontiersmen
TRes Icon team resource neutral 0.75 x initial cost x %HP left
Duration 6 seconds
Recycle enables the Marine Commander to return a portion of Team Resources by recycling a structure. The recycling process lasts a short duration, after which a maximum of 75% Team Resources used to create the structure is refunded. However, the amount of Team Resources refunded depends on the remaining health of the structure on recycle completion. The higher the structure's health, the more resources are refunded.

The technology behind the Infantry Portal concept is based on current scientific experiments with teleportation, or, more accurately, the successful transfer and encoding of information from one atom to another. Essentially, when the photons have been triggered in just the right way their parent atoms enter a quantum state in which atom B takes on the properties of atom A, after which process atom A disappears.

So, in the case of the infantry portal, all of the physical information of marine A is imprinted onto empty-marine-blob-of-atoms B, which has been created from the similar 3d printing technology used in the armory. Then the consciousness of marine A is downloaded into marine B, all in the space of several seconds.
