The Gruntz team have posted a video of their demo games from the Warfare show.
From their announcement:
Gruntz was supporting Ground Zero Games at the UK Show “Reading Warfare” and I attended on both days over this weekend. I managed to run eight participation games of the Gruntz 15mm SCI-FI wargame with public gamers. After learning from the last show game, I decided to reduce the number of figures on the table to keep people focused on the core rules with a Kra’Vak alien beach attack on some GZG New Israeli troops.
