Colin Moriarty tweeted that a source informed him of a Socom project which sounded "bizzare" in a positive sense.
He then stated in a podcast that Guerilla are working on Horizon and another 3rd person project and that people should be able to connect the dots as to what it is. (He hasn't teased anything else recently).
I also asked him if it was Socom on Patreon and he said "You never know ".
Also, they hired the lead of R6 Siege so clearly planning something tactical.
yes I speculated something like this as something killzone is in the pipeline. something like kz2 mp but brought to current standards and graphics. even though they do keep pushing narrative games i'm sure new management wants something service based.
its the most logical ip to choose.
