Try Helldivers if you haven’t yet. It’s a twin-stick shooter by the same people. Instead of a story campaign you progress through semi-random campaign maps to reach the enemy homeworld and blow it up in the name of Space America and Managed Democracy. It’s a spoof on American fascism in the spirit of Starship Troopers. The shooting is pretty tight, there’s a ton of weapons and equipment, and each player gets to choose a set of “Spells” that you call in Magicka style - airstrikes, mechs, special equipment. It’s a lot of fun and, like magicka, blowing up your friends and then casting the rez spell is a big part of it. Higher difficulties are extremely frantic as you struggle to deal with hordes of enemies and your weapons get so powerful they’re almost as dangerous to you as the badguys.

And give it an RE4-style unlockable campaign where you play as the Juche commando who secretly influenced many of the events of the main game
