Best thing on here, easilly.
This is by far the best, and most well polished and presented game on newgrounds. Anyone born in the Nintendo era of gaming would be lieing their asses off if they said they didn't enjoy this game at least a little. Anyone who thinks this is hard both sucks, and has obviously never even HEARD of the Contra series let alone played the US version of Hard Corps.
Anyone that liked Contra, or more recently the Metal Slug series, owes it to themselves to play this game at least once. And as someone who would willingly buy (a non-censored version of) Metal Slug I can truthfully say I would buy this for any modern console the second I saw it.
Oh, and by the way streetlight, most of us that liked this game took our heads out of our cracks before playing it.
