Rats in the walls has an agile game system based on 2d6. Where a roll of 8+ will mean a successful roll, although it gives freedom to several modifiers and interpretations of the consequences of the roll by the Game Master.
The character sheets flee from be complicated: the values are attributes, profession, reputation and equipment
Like other games based on Lovecraft‘s world, Sanity will be present in Rats in the walls too. The Sanity value represents the character’s ability to face threats from beyond. However, in this system, sanity can lead to three consequences:
- Do something stupid for 1 turn (transient madness)
- Losing consciousness for 1d6 turns
- Act normally in exchange for a “scar” that will mark the character.
Losing sanity points or accumulate too many “scars” can lead the character to become an NPC.
Magic will be present in the game Rats in the walls because it will easy to use. Whenever the character gets a spell, he can use it if he opens his mind to “creeping chaos”. In return the character can lose sanity and there is always a bad consequence if you use magic.
