That's a weird question because to be frank here I kind of like some "realism" from the weapons but not that much in the way as I do think some of the tech can be really sci fi or more what we can see in games like UT, Wolfenstein, the 1st Soldier of fortune for example. And what I mean here is "Some" realism like weapon reloads, weapon accessory mount (Upgrade ? Customization ? Both ?) And also ammo swap ? Fire modes ?
But also things with more sci fi / fictionalized elements like beam weaponry, plasma, but also things with more imagination like disks, metal rods, gravity based projectiles, and also combos like a ion gas plasma can do all sorts of weird things when shot with lightning or a laser for example. Also projectiles that can bounce and have a tactical use even if the game is fast paced they do work like remote bombs and other things.
But also makeshift guns because in certain areas maybe a standard equipment won't be available to some extent and so you have to either make that equipment pass to use it or have to stick with those improvised weapons.
