Don't waste your money on this POS game. HAWX 1 is fantastic IMO, a fun arcade flight game with solid gameplay, definitely recommend it.
HAWX 2? Hell no.
Not only do you have to put up with installing the Ubiscam launcher, you then have to deal with their iron fisted DRM service to even begin playing. God help you if you can't get your copy to register on the Ubiscam launcher, or else you have to buy it for a second time.
Lets add in the fact that a majority of people can't even get the Ubiscam launcher to launch in the first place, meaning they can't begin to deal with the other headaches that lie in wait. It requires a 100% internet connection at all times if the launcher is in online mode (even if playing single player), meaning the slightest glitch in your connection instantly boots you to the menu. And that's assuming you can even get the single player to start! 99% of the time you'll get booted back to the menu after the first three intro scene sentences for no reason. OH, and you constantly have to validate the cache, basically every time you want to launch the Ubiscam launcher to launch the actual game.
TL;DR - Ubiscam doesn't give a s**t that the game is bug ridden and worthless. DRM is crazy, requires Ubiscam launcher to play. DO NOT BUY.
