This first submission is just plain awesome
Very awesome for a first submission, I guess you're realy happy because you got an award on your first submission and I would be happy too if I did since usualy only a few peoples get the awards so having it on your first submission may be realy friking awesome.
Even if the graphic are not perfect I don't realy thinks that matters since this is a parody and not a serious short, plus this is your first submission so I guess it's kind of normal since you do not have much experience with newgrounds. The jokes where all funny except for the tank joke was not funny at all in my opinion, but some other jokes where realy funny such as the I HATE HELICOPTERS one wich is my favourite. There's no voice acting so you migh usualy loose points because of that but on the other hands I think it is harder to use the game's original voices since you have to make them fit to the movie and you do not have the liberty to make them say exactly what you want so I guess I won't make you loose points for that.
Realy great work.
Oh and to answer to GenJi94 comment to say things in the game it first depends if you got the game on PC or on Xbox 360, if you have it on PC you got to hold Z or X (default commands) and then a windows should open and you may choose what you want to say, if you have it on Xbox 360 then press the X button, in that case what you will say depends on what you're aming at; if you at a teamate you will call for is character's name, if you're pointing nothing in particular or pointing normal infected your character migh say somthing like LOOK OUT or something like that, if you're aiming at items then you might say something like PILLS HERE, WEAPONS HERE, AMMO HERE, etc. Sometimes the characters say some things by their own without having the player to push a command or anything
