I've just adapted a Starhammer model to replace this ugly Astarte tube. Even with the same equipment he is slightly better. Thanks to his skeletal construction turrets have wider field of fire but it's really hard to find good place for main guns and turrets.
Screen shows "mk2" version with 2 main guns (firing forward), 2 main turrets, 4 small turrets and 4 systems (and a little logo on the side
).
