Hi there

It would be nice to see a corridor type cheap room, kind of placeholder, which should have the ability to expand into any room later.

lvl1: tunnel 50 caps - very high radroach infestation chance, no fire chance (like a cave in the rock) very little or no electricity need /no lights - negative effect on guards happiness/

lvl2: corridor 100 caps - high chance of radroach infestation, little chance of fire (low grade corridor) low electricity need /low lights - some negative effect on guards happiness/

lvl3: reinforced corridor 500 caps - low chance of infestation, low chance of fire (nice looking corridor) moderate electricity use /fair lights - no negative effect on happiness/

build any room should work on the corridor cells with 50% refund on the corridor's price (they don't have to dig)


guards should be available to patrol/defend it like at the vault door

the point is, if you build a room in one cell and you don't want to expand it to 3 adjacent rooms but wanna keep the space, then you could build 1-2 corridors next to it and then you can build an other type of room on the same floor
