- A helipad and exterior tile will allow a starting and/or exit board for the players to work with.
- A vehicle hanger/ garage for a large relatively open space.
- A command and control room with monitors along the walls.
- A few barracks/ sleeping spaces with toilets and officer's quarters.
- A cafeteria for a large relatively open space.
- The obligatory surgery room and science lab, filled with cadavers and tubes with aliens/ face-huggers.
- A massive power chamber or large open space with gantries for multi-level combat.
- Some storage rooms or smaller rooms with machines in them.
- An armoury for the base defenders to stash weapons and allow players to arm civilians in-game.
Much of the interior obstacles(tables, barrels etc.) will need to be mounted on separate bases to enable me to change interior layouts from game to game.
I have decided that the obstacles will need to be in three sorts. Category 1: Does not impede movement, or line of sight. Category 2: Does not impede movement but blocks line of site. Category 3: Blocks movement and line of sight.
