I’m the marine now, tell me what to do. This place is going down, the UAC Mars base. The hell creatures, now dubbed as XX121 are crawling all over this place. You must survive, through some alien technology. Rest is the same. This should integrate well into Alien movies. The hell dimension has materialized itself as the Alien species, XX121 here on Sevatapol. But earth is over now, we’re in deep space, that’s all. Don’t go back home, nothing remains in that home solar system.
