It all remains speculation tho, untill Respawn comes up with some actual dates. This means that TF|2 takes places somewhere between 27, is my best bet. This is because during TF|2 Simalucrum are known and in use, while during TF|1 they are not a thing yet (Only hinted at, that Hammond is working on a new and improved form of Spectres). That means the assassination probably took place between 1 and 5 years before the events of TF|2. I thunk during the assassination Simalucrum are not widely known or used, based on the reporter stating that the Simulacrum project is taking off and Marcos not knowing what Revenant is ("What are you?"). The assassination of Marcos was 25 years ago based on the cold case murder report.
That means the events of TF|2 are during 2715 or even earlier. The current years is 2733 and the war ended with/after the Communications Blackout in 2715. I think can assume this from the new info. I’ll just copy/paste this here from one of my other comments.
Now, Cooper being 23 does make his skill as a pilot seem a little fishy, but it is important to remember that Tai Lastimosa had been mentoring him to become a pilot for a while. Adventure Gamers have published a review of SIMULACRA 2 and rate it as Uneven, at this time the community has not provided a rating for SIMULACRA 2. SIMULACRA 2 has a Live Action style and uses a Touch control scheme. I find it hard to imagine him waiting until his mid 20s before joining the Militia to fight the IMC. The show, of course, is Star Trek: Deep Space Nine (DS9) and its allusions to the Holocaust, Jewish history, and the era of World War Two are central to its. SIMULACRA 2 is an adventure game, released in 2019 by Kaigan Games. If he was around 30 by the events of Titanfall 2, then he would have joined at around 25 this makes little sense considering how passionate he was about liberation in the intro, as well as throughout the entire game. This would make him 18 when he joined the Militia, a reasonable age to join. This means that by Titanfall 2, Cooper has only been in the military for around 5 years. In The Beacon, we are told by BT that Fracture was one of Cooper's first ever assignments as a grun- sorry, rifleman. Now Cooper being 23 seems a little ridiculous considering he looks about 30, though it makes more sense when we look at his military history. If we take Titanfall 2 to be 2710, which I see as the most likely date, then Cooper would be 23 in that game. Furthermore, Cooper's age also supports this. When we take part in an official session, we avoid teamkilling, shooting indiscriminately, romping around in vehicles (particularly helicopters and jet planes) or trolling with explosives. Considering how common Simulacra are in that game, it makes more sense for it to be afterward.
Hollier calls this passage from Le my the et lhomme by Roger Caillois. Thanks to the new trailer, we now know that Hammond Robotics were the ones who invented the Simulacra, which were not present nor public in Titanfall 1 meaning that Titanfall 2 must take place some time around the events of the trailer. Stories of the undead elucidate the relation between the obsessional and the simulacrum. I think you're right that Titanfall 2 takes place after the events of the trailer, just a little further away from the Apex Games than previously theorised.
