The comics where Aliens took over earth or were even mentioned taking it over were considered non canon as soon as Alien 3 made its debut. The rewrites were considered non canon after Resurrection and especially after Prometheus. Prometheus taking away the Alien homeworld and making the pilot race into engineers. Now my Alien/Predator comic box is set up to be canon friendly, so to speak, with the Alien and Predator cinematic universe. Anything Predator takes place from the past to now. Predator featuring Dutch's brother doesn't fit as its never mentioned in later movies. Something like Aliens Earth Angel fits because its an isolated incident that wasnt documented by anyone. Aliens vs Predator set on Ryushi fits before Aliens as it ends without anyone even bothering to really investigate the incident. Same with Avp Duel which can be set almost immediately after Alien 3 AND of which legitimises quotes from the Colonial Marines Technical Manual. With that in mind, "the company" was pretty much forced by Colonial admins and the military alike to forewarn its colonies of the XT threat. Only higher up's having the facts leaving regular joe's passing along rumors. Lets not forget also about company cover ups such as Aliens Berserker. After Avp War, which brings Predators into the spotlight, We get the Fire and stone series which also isnt documented by anyone. Counting the big deletion as canon fortifies the fact that the military barely knew what xeno's were and where to find them. With Predator Incursions inclusion of another research vessel experimenting with xeno's a few years before Resurrection, i'd say its a solid fact General Perez was one of possibly a few army stooges with orders to investigate rumors of past xeno incidents and collect specimens if found. Perez getting lucky and finding Ripleys tissue samples on Fury. In short, if the incident isnt well documented or can be considered a cover up, it fits perfectly before Resurrection. Now, as Incursion states, Xenos and Predators are well known in the new farther future so anything where people mentioned Aliens as if the whole of humanity already knew fits perfectly in that timeline.
