Introduction
Alien Tunnels connect to points on the map via a tunnel. The length of the tunnel is fixed and does not change with the distance between entrances.
Tunnels are limited to 1 per Hive (up to 4 total) and each Tunnel is limited to 2 entrances. Both teams can use the Tunnel but Marines suffer a corrosion effect that deals damage to their armor as long as they are in the tunnel.
Once the Tunnel has been upgraded to an Infested Tunnel, both entrances will become Infested Tunnels. As long as one entrance survives, both entrances will be Infested, but if both entrances are destroyed, they must be upgraded to Infested Tunnel again.
A Tunnel entrance must be placed on Infestation, but will not lose hitpoints if it is no longer on Infestation. Tunnel entrances will only grow or be built by a Drifter on Infestation, but Gorges can build Tunnels that are no longer on Infestation.
