All I can say for this game is: "Wtf is this?" Please change this game to something other than a mere flash game with no standing qualities to be deemed as a fun game.
TDP4 is one of those flash games that should never be made ever again. Abundantly filled with the gore of modern shooting games and just countless hours of the same action. This game just lacks the basic requirements of a dependable flash game.
This game is a creative mess of bourgeois programming, sloppy graphics, and riffraff action. The plot is very simple, in fact too simple. There seems to be no certain purpose to this game other than a gore fest of space things and gratuitous shooting violence.
