The alleged GTA5 screenshot features what appears to be a mini submarine. For what it's worth, a similar-looking vehicle seems to make an appearance in an official "Grand Theft Auto 5" screenshot released by Rockstar Games last week, which you can check out below.

Also, the bridge you see behind the mini sub in the supposedly leaked screenshot may be the same bridge that appears in this official "Grand Theft Auto 5" artwork below.
