Genre: First-person Survival Action Puzzle Horror

Main Idea:

The player found itself in a set of rooms where a curse is spreading, generating Undead which when shot to death duplicate, player will need to use surrounding to solve fast pace puzzles and avoid dying or being Cursed by the touch of these creatures. Being cursed will create difficulties for the player but they will still be able to continue and find a way to exit the cursed dungeon.

Reference of curse effects on gameplay - Curse of the dead gods

Spreading mechanic

• Enemies undying mechanic: Enemies when killed revive and duplicate, shooting enemies will be use a CC (Crowd Control)
• The curse spreads: Player will need to treat the curse if affected by it or succumb to madness
• Darkness Beckons: A darkness spreads continuously which puts a timer on the player on advancing further or be affected by lack of vision and potential cursed rebuffs

Core Pillars

• Environment as a weapon: since player cannot kill the undead with the guns they will have to use their weapons to modify the environment, trapping, immobilizing, etc
• The curse spreads: while being cursed this one will start spreading through the body, affecting player execution of actions, perception and such. Players will need to halt at all cost or succumb to madness.

Developer Notes: little but well crafted mechanics with a lot of reliance in level design, progression and other systems could inherit similarities to roguelike genres
