The last new concept mission appeared and is not translated. Subjugate the Thing Nesting in the Forest.
Its a continuation of Bizarre? Subjugate the Odd Pest! with lots spider web panels and those killer caterpillars that catch you if you don't adjust speed and use Nerine or somebody that has the ability to negate those. Worth 5 FGs.
