This gamemode idea would essentially be a 2 1/2 D Half-life 2
The gamemode would have a slightly cartoonish approach to HL2, having it’s own campaign to play. It would be for singleplayer or multiplayer. It would be played as a side scrolling game, but is in 3D. It combines elements from HL2, terraria, and Super smash bros. You can jump quite a bit higher, move faster, and solve puzzles. The basic goal of the game is to get to the end of the level, by solving puzzles and fighting enemies.
Movement would be controlled using the A + D keys, and space to jump and ctrl. to crouch. Aiming would be pointing anywhere on the screen, and your character will try to shoot at that location.
The maps will be dedicated side-scrolling maps with 3D elements in the background that can hurt or help you. They would consist of 3 total levels per bsp, getting harder each level, and would have many interior and exterior environments, ranging from spring to winter.
You get money from killing enemies which can use in a shop where you can purchase weapons and ammo, as well as other items (such as hats) These items would not be permanent and would reset after disconnecting or quitting, but are cheap enough to purchase quickly. Your money, however, would be tied to you.
I’ll admit one thing, I CANNOT CODE JACK, but if someone is willing to do this, I’d love to make the maps for it.
