So, a thread here in the lair of the First too.
For reference here is the first (of 4) board I’m making:

I added decals, dirt and Mars Dust. Will add some dirt and stains to the (Greenwing) Companies room and I hope to get the corridor grating put down tonight. And then weather the grating.



For future boards:
Holes in the grating.
Hatched in the floor of rooms.
Stone floor and wooden floor.
Chains, spent ammo etc. on floor.
Missing tiles showing pipes and pistons and stuff underneath.
One room a cell. Room 42? 101?
Oh and I did get some patterned plasticard to use too

And this is what the next three boards will be (based on):



Ideas and suggestions are welcome but bear in mind this is being done on a budget

Ways to make it more ‘First Legion’, etc. A name for the hulk, that I can paint on it?
