Warlord Games has posted up another preview of the upcoming Battle for Xilos expansion for Beyond the Gates of Antares. This time around it's another Ghar character in the form of High Commander Karg 12-40-9. You thought the previous Ghar guy had an impressive rig he was riding around in.
High Commander Karg is a brilliant strategist, but he's also a bit of a coward (some might call it "overly-concerned with self-preservation"). So while he can help remove pin counters to units around him, if an enemy gets too close, he's going to run for it. The troopers piloting his walker around also know better than to disappoint, giving them a reroll on Initiative tests.
