So I bought a MegaDrive Justifier the other day for only $4, and want to pick up the Lethal Enforcers games. However, I keep seeing the original as cartridge only. I checked the DP Guide, and it said that when complete, it should come with the gun in a big box.

Was the game ever released as a standalone clamshell/cardboard case? Is it only available separately from the gun as cart only?

I know the sequel came in the standard MegaDrive packaging.
