Splashcoat,  I don't believe there is any particular "theme"  It's just covering the different genres. 

CATEGORIES

ARMOR (new build)

AIR (new build)

SCI-FI (new build)

VEHICLES (new build)

FIGURES (new build)

DIORAMAS (new build)

EVERYTHING ELSE (can be old build)

SPECIAL THEME  - AFTER-LIFE (new build)

Anything that finds a use after it's normal life has come to an end. From tanks made into firetrucks, to suburban mini-vans made into death machines, to zombies, to the world after man, to a rusty Crown Victoria and everything in between.

Includes machines/vehicles 'reconfigured' for alternate uses, 'MAD MAX' style vehicles and general post apocalyptic mayhem.

All categories above:

Out Of Box, scratch built or somewhere in between is allowed.

After Market products are allowed.

No scale restrictions.

This was taken off the contest link at the top of the page.  Most anything goes as long as it's a new kit ecept for the last catagory "everythin else".

I am sure someone will chime in here if this is incorrect. :

Hope  this helps ;D
