Game On! Brief- Ideas

We've had a new brief, focusing on creating elements of a game as a proposal, such as concept art, models and animations. I'm working with another in my class, and we're currently working on ideas. I want to focus on concept art mainly, without doing any animation since the briefs beforehand have been animation heavy. I'm interested in creating a survival horror and we've decided that it's the direction we want to go in.

Notes

Survival horror, similar in style to “Amnesia: The Dark Descent”.

Modern day setting (2010-2011), abandoned town settings, first-person perspective. Night-time environment, foggy. Dry conditions (no rain, snow, etc). Lighting is ambient, character has no light source. ‘Everyman’ protagonist, 40's, defenseless against the threats. Focus on avoiding enemies and solving physics-based puzzles.

Story related to fire, disaster. Possible town setting is severely damaged by unknown fire.
Enemies are individual and there is no duplication of enemies. Each enemy looks unique, but due to the player character being defenseless, the monsters are invulnerable. Possible 'family' type of theme to be incorporated, as well as a 'burnt' or 'scorched' look. Themes of suffering, madness and guilt.

Suggested title: Ignis Lake ('Ignis' is Latin for fire), meaning 'Lake of Fire'.
Suggests duality and opposition (as fire and water are opposing terms) and hearkens to punishment
in the afterlife for the wicked:

"And the devil that deceived them was cast into the lake of fire"
Revelation 20:10
