I dont mod soo the best i can do is this list that hopefully someone do it,atleast one of them (in order from the most wanted to less ones) :

-Plasma thrower : with its respective stats but double ammo and with its singular explosive proyectiles.

-Homing bullets/proyectiles: rockets , laser and probably canon balls going directly to enemies (this one is just to mess around becouse of OPness).

-Ricochet bullets/proyectiles: this one could be apart to bullets and lasers.

-buffed/better weapons: not like insta kills just more fire speed / damage , just a little bit and a new version of them.

-More details: to weapons, maps, enemies (especially the red demon) that have a little touches to make them look better.

-Altern fire modes: for some or every weapons to have a different case fire mode.

-Sniper rifle with piercing bullets: could be replaced with a laser rifle that go through enemies and maybe walls.

-Cooler boss battles: until now everyone complain about the boss battles being boring but it would be interesting that someone actually remaster them or change them, one addition could be patterns to doge.

-Doom 2016 mod pack : with weapons, some enemies replacement or addition, music, powerups and maps.

-Quake champions mod pack: weapons replacement , powerups and deathmatch maps(maybe the deathmatch maps could be redone to be survival maps).

-Huff campaing: remember that guy Huff from Serious Sam DD, maybe a player model with its sounds but it would be awesome to have him in a custom campaign or with a sidestory secretly or accidentaly helping sam.

-Samuel free world map pack remastered: that modpack from serious sam classic revolution(that one that take years to load) could be interesting in hd version with some changes maybe.

-Unreal tournament weapons: the old school one or the new ones , with its stats and effects like flak cannon doing both fire modes.

This list is just for someone that need an idea or wanna make a random guy happy.




To anyone who decided to made one of this ideas : i love you.
