Strains are variations of the xenomorph you play as, changing up their play style to something either slightly or completely different to the normal xenomorph. This allows you to change your play style to experiment with.
You can pick your strain from the get go if your caste has any strains available to them. When you evolve you will lose the strain you previously picked. Each Xeno can purchase one Strain available to their caste and they are permanent.
Under the Alien tab you can buy strains for yourself with the Purchase Strains verb.
