Pixel Gun 3D but it's a 8.0.0 CAMPAIGN Gameplay PART 1 

This is not the first video where I play through old versions of famous games, but the old pixel Gun 3D surprised me with the fact that it differs from the current version in many ways.
In early versions of PG3D, there was content that was later removed or replaced in late versions. Among the removed ones are maps, music, campaign bosses and guns.
