What is Invaders: Corruption?

Invaders should be my personal take on the tried and true genre of arena-shoot em ups. It will involve several fresh Ideas to spice up the core gameplay mechanic, to add replay-ability and new gameplay mechanics for the player to cope with.

The game will feature an retro look, which besides being popular nowadays, also serves well to highlight the game's main feature:

Procedural content

Most content for this game will be generated on the fly. The generation will based on a seed value, which the player provides. Giving an indivudal experience to everyone playing. Of course you can exchange particularly interesting seed values with your friends.

This means obvious things such as ship graphics, effects and enemies will be generated procedurally. This means for example an almost infinite (Okay okay ... 33,554,432 only!) amount of enemy invader looks. It will also mean emergent AI behaviors as AI "parts" will be mixed together procedurally as well. Which brings me to:

The corruption

The name giving feature of this game is the so-called corruption. It will slowly spread from corruption-nodes which the player must keep in control, to remain in command of the arena.

The corruption will glitch sprites (think NES sprite errors) as it goes, turning normal enemy invaders into unpredictable hazards. Stats such as Health, AI and appearance will be mixed amongst other nearby corrupted invaders, resulting in newer stronger enemies. To survive the player will have to adapt new strategies.
