===Vents===
[[File:TGMC_Vents.png|100px|right]]
Under the Alien tab, there's an option that says ''''crawl through vent.'''' Clicking this within one space of a vent tile will allow you to enter the vent after a short delay (4 seconds). Alternatively, alt-clicking the vent works too. While in a vent, you can see the network of underground atmosphere pipes that run throughout the map. These pipes have their own unique layout in each map, and you'll have to learn them by exploration. You can't be seen or hurt while in a vent, but you do make noises and can be picked up by scanners.<br>
Use vents to scout the map in safety, gain access to restricted areas, and ambush unsuspecting targets. Note that vents can also be welded shut by a marine with a welder, making them impassable. Xenomorphs can break these welds by using harm intent on the welded vent while outside the vent.
