Initial mood board / visual references.
For my proposed SE2 Combat system - less is more.
Ballistic Rapid-Fire Weapons:
HMG - high damage. RPM increases when aiming (right-click) : Heavy Bolter mechanics from WH40K
Gatling - large spread, less damage, less range, turret slow to turn - but hit scan? This is just a current idea- Hit scan would allow the best anti-missile defense and may be easier to function in the game code!
