Someone remade the first level from the original Contra using Half-Life 2. You all should be extremely familiar with this level as you've died at least a thousand times in it. At least.
It's pretty awesome getting to see this level from a first person view. It's also a nice change of pace as I'm sick of seeing that stage how you normally view it. It's not that I suck at Contra. It's that I'm freaking impatient and just want to pew pew pew through the entire game as fast as possible.
What? Don't f**king judge me.
