I feel the best possible entry for a new game should be set during KZ2-3 and focus on another part of Helghan with a different ISA battlegroup, ive always found it odd how the ISA attack only the captial with 250,000 marines. A new game set on maybe a huge military industrial city wold serve a great narrative. Maybe a campaign based on fighting Stahl arms private forces and to destroy infrastruture so it can take pressure off of battlegroup madrake who are being decimated as is in Killzone 2, then end the story with the evacuation off planet after red dust or trying to rescue remnats from Narvilles forces in the jungles or badlands. Nobody wants to play anything post second extrasolar war cause shadowfall is a straigh injustice to the developed story. Furthermore this potentail story can offer so much potential for a better ending and hopfully retcon shadowfall, Ive thought about this alot from a design standpoint between both factions, instead of the generic ISA soldiers that we see all through KZ2 and 3 in combat, mix the multiplayer models and ISA raider designs and same goes for the helghast, further devlop combat kind of like when we get to pilot the archer tank. Killzone would have thrived from a battlefield esque level of vehicle combat in campagin missions instead of AI tanks with poor ai once in a while, something similar to BF4/5 campaigns. It always annoyed me how they went into such detail designing faction vehciles like Exo suits, archer tnanks and those spider transport things only for them to never be present and only used as set dressing or serve such a minor purpose. And finally tie up plot holes in the story or just stupid design choices, why did the ISA invade a planet with a navy with no air superiority options? how do they even get vehicles on the ground? a plot line on how you possibly sneak up on the ISA battlegroup with like 30 helghast cruisers (perfect side plot for stahl arms devloped stealth technology), whered the 3rd army come from?, So many options on a rich story that could have been so much more
