Doom: The Dark Ages is introducing big changes to combat because id Software came to one core realization: "Every projectile mattered in the original Doom"
Creative director Hugo Martin on how Doom: The Dark Ages is a spiritual successor to the original game, and how the Saw Shield will completely upend your expectations
See this and the dark ages theme makes me think we actually are going to see them try to pull off a complete FPS arsenal with no hitscans, or at least no pure hitscans.
If it works I could see it being a bold new direction for FPS design, why worry about balancing snipers if even your longest range weapons are still projectiles, also, why limit your arsenal design only to guns now that you don't actually have the need to create that point and shoot sensation the same way. You could build an entire "FPS" that's just snowball fighting and the different "weapons" in the arsenal are throwing implements.
Sounds kiddish but imagine being able to crack open a cozy game fps with some hot cocoa.
Honestly my first mental picture was something more like a really low rate of fire Splatoon except more about knocking down enemy "fortresses" instead of just coating the other side since... it's snow, it's already on both sides.
Different weapons would be stuff like slings for range, or a shovel for busting down snow castles, maybe it has a charged up projectile where your character gets a whole shovel full of snow and then lops it overhead to try and nail someone with an air mailed avalanche.
Also have an actual gun sometimes show up on the map but if you grab it all your shots miss for like ten seconds because funni.
That's what the heavy mortar gun was all about : let the scout zoom around the map pointing targets for you to destroy, hidden behind a hill from the other side of the map. Such memories! :)
I used to sit in the team deadstop mumble server and play pickup games with them every day. I could only kinda keep up playing medium and heavy offense, but it was one of the best gaming experiences I've ever had!
