The designs and visuals I made last year for Matagot company refreshing popular and high rated board game "Captain Sonar".
My role was first to prepare the boxart but soon it expanded to the designs of futuristic submarines (of two opposite sides) but also cover screens showing submarine interior compartments. To design the submarines I used parts from my earlier projects, so You can easily spot plane parts (from my Lancaster, B-17, B-29 or B-52 models) and even dentist chair I once modeled.
I also used great kitbashes:
SCI-FI WIRES KITBASH PACK 80+
Sc-Fi Computer Console Kit
48 REPETABLE SCI-FI PANELS
