Here some strewed brief ideas
1)_Since in Helldivers weapons have the latest technological achievements such as lasers, electric arc, plasma and so on, how about adding a new technology? Sonic or Ultrasonic Weapons (USW)
Red Stratagem = Ultrasonic Blast: When called it emits a shockwave, which expands from the center, pushing and sweeping away anything. It is not an explosion, it does not create damage to enemies or troops, it simply takes everything away from the point of call up.
Primary Weapon = (Name?): This primary weapon belongs to the explosive class, unlike the CR-9 Suppressor, it emits fan-shaped shockwaves and has a short radius, like the symbol of Wi-Fi. (I admit, this is a bit forced).
2)_When you unlock all enhancements using the Research Points, then they accumulate and remain unused. If only were other ways to spend that amount, like the ability to unlock new pages in the Encyclopedia inside the ship. Adding tips/tricks or weapons/stratagems info (ported from the armoury) so we can read it well.
3)_A new perk that constantly keeps the mini-map open (perhaps this prevents a main feature of the game, however it can be quite challenging play without the weapon hub).
4)_I think the AC-22 Dum Dum is a little under-powered, is there any chance to make it “low-profile-anti-tank-rifle”? i mean, there are far superior primary weapons, you can’t even scratch a Brood Commander with it, because its real weakness is the not being able to take aim, (i mean, the Helldiver rotate too fast to perform a precises aim) and the few projectiles scored are not sufficiently “harmful”; even because explosive isn’t in the bullets caratteristic but you keep like that. Could it be adapted for medium/high-armored targets? Would be enough to slightly increase the damage and go from 4 standard magazines to 3 standard magazines (from max 8 to max 6).
And even if already mentioned I definitely give a thumbs up on this:
