Yes, that's cosplay.
This is Aussie cosplayer Scrap Shop Props with a 1:1 Doom Space Marine, which just won best in show at the Supanova expo in Sydney.
Whilst we were at @paxaus we had the opportunity to catch up with @magic_missile_studios again! He's always fantastic at highlighting all the small details you spend far too long on. We didn't have long on these @quake builds, but we're very happy with everything we did. #amd #quake #quakechampions #bethesda #doom #DoomSlayer #cosplay #foamsmith #proptarts #ripandtear
If that's not enough, they're also responsible for one of the biggest and best Reinhardts I've ever seen, that comes complete with a jet engine effect at the back.
