I know most of you that are interested in this game already own the rules, but just in case:
The 'print-on-demand' (black & white cover) is no longer available.
The errata'd faux leather (green cover) is now OOP and only available from stores that have stock left (pretty much OOS in the UK).
There is a new hardback (red cover) which is the same as the green one, with a few typos corrected, due soon via https://www.modiphius.com any time now (they've started sending out to those with outstanding orders).
