The Queen, the Hivelord and the Drone all share the ability of secreting resin in a manner which allows them to create structures. This ability is incredibly important, as this allows them to create Hives, big resin chambers in which Xenomorphs can live, recover, gather hosts and protect Larvas. This environment hostile to non-Xenomorphs can also be used as a defensive position, allowing Xenomorphs to shape the battle to their will as they get pushed back.
All resin structures, outside of the Resin Sac, must be built on existing resin weeds. This means that building Hives is a methodical process, where weeds are first planted to accommodate local structures, and those weeds then serve as the foundation for other, more complex structures.
Resin is relatively tough, able to sustain some punishment from firearms, explosive shockwaves and sharp weapons before falling apart. It is however notably vulnerable to fire. Resin structures can only be placed on a stable surface without existing foliage. Artificial flooring and sand are two notable examples of surfaces that can be used. Grass and any tiles containing water are notable surfaces that won't be usable.
Only one resin structure may inhabit a chosen tile, not counting Resin Sacs. As such, it is impossible to stack a nest and sticky resin, or a door and sticky resin. If a structure is getting in the way, you can simply tear it down.

|Thick Resin Walls are a major upgrade over regular Resin Walls, exclusive to the Hivelord caste. While normal Resin Walls will tend to fall rapidly to enemy fire, Thick Resin Walls will usually hold up for much longer, for no added cost to the Xenomorph building and maintaining them. This makes a Hivelord invaluable when building Hives and forward positions, and can potentially stall Marine advances if positioned properly.||
While it is easy to throw down resin, it is important to try and plan ahead for what you want to do with the space you are using. Are you simply weeding the terrain? Are you planning to supplement existing structures with doors and walls? Are you making a full Hive chamber? Is it going to be a defensive chamber, a nest, maybe a storage chamber for Larvas and dead bodies?
Not planning ahead can lead to serious errors, and once a Hive is well underway, it is extremely time-consuming to tear down resin structures to try again. Be careful about the space available to you.
Some common tips to help you build a Hive worthy of your Xenomorph Hive:
- As time goes on, any area that isn't weeded and can be, should be. Weeds are the life and blood of the Hive, and as the Resin Weeds spread and extend through the colony, the area where Marines can safely navigate shrinks proportionally. In the event of combat, remember that even the smallest patch of weeds can be used to rest and recover plasma and health.
- An average chamber should be fully sealed with Resin Walls and Resin Doors. A good hive should have wide entrances to make manoeuvring easier and multiple exits to ensure that xenomorphs don't get cornered and trapped by the USCM.
- A wall of Resin Walls and Resin Doors is the most basic defensive setup. While it can be destroyed with concentrated fire, it allows Xenomorphs to break line of sight and provides easy locations to ambush marines. More advanced tactics can involve stacking walls, or creating single Resin Walls for Xenos to hide behind.
- Usually, every nest will be a trade-off between space efficiency, easiness to guard, and concentration of hosts within a chamber. As hosts that get up can help others break free, extremely large chambers are unadvised due to humans being able to coordinate any escape effort. A more conservative setup is to use a square of four nests, preferably not full of hosts, with two guarding castes on each side to quickly put down any revolt. Small nest cells can always work, assuming you have unlimited space to work with.
- Sticky Resin is a useful tool to hamper human maneuverability inside the hive, with the drawback of restricting construction on the tile it is built on.
