Hello! I need your help!
I looked in the file "researchs" that the manufacture of extream chemical grenades should be investigated AdvXenoDNA. And it needs to be explored Rogue, Stalker etc. What is this xenomorfs? I have 4 phase, and such xenomorfs I have not seen!
Another question ... In the fourth fase there is only zeta rippers, rippers from earlier phases are missing? I can not get the important technology in phase 4, because it is not captured rippers of the early phases, which are needed for research!
