Helicopter physics games have been around for millennia. Primitive cave paintings show neanderthal man struggling with the vagaries of WASD control configurations and floaty flying avatars.
Actually I might just be getting confused with 1992 shareware title Ugh!, possibly the best game about flying caveman taxidrivers ever made. That thing was where it was at. In fact, while we're taking a leisurely stroll down Nostalgia Avenue, why don't you go download Ugh! for free and get your cro-magnon on old-school style.
But that's not what I'm posting about today. For those of you for whom 16-bits is just not enough bits, there's a fancy-pancy modern browser-based helicopter game which I just now this minute discovered. It is called Hanna In A Choppa and it is, in the vernacular, "rather good". The frustration of this type of game has always come from when you inevitably ram into things, avoiding which tends to be the point of the game. Hanna has a nice balance, failing you for only the most spectacular crashes, but rewarding you with shiny achievements if you go the extra yard for a perfect flight. It's also got a wide variety of missions, starting with predictable "navigate this tight corridor" levels but working up to rescue-at-sea scenarios and the provision of monster-sized hairdressing.
Hanna In A Choppa is available through Kongregate, and probably some other casual gaming portals. Y'all should go play it some. I'm not kidding. It's delicious.
