Not much room for add-ons. Not that they didn’t try.
I still have the White Dwarf issue where they gave rules for using regular Space Marines in place of the Termies. Loads of fun and very bloody!
The tiles are all first edition, it belongs to Ninjasaurus who bought two copies of the game to have more to play with!
Envious! I have the most recent edition (with all the stuff you have to paint and crazy poses for the minis) and honestly I would MUCH rather be playing with the vintage stuff instead.
