I've played through this now, but first a couple of disclaimers:
 
 1: I played with godmode because I glimpsed in the readme that hard was insane and easy was hard. This, I've come to learn, means that it is ridiculously hard and I couldn't be arsed to play it properly at this time of night. Thus I won't be able to make any formal statement about the gameplay.
 
 2: I didn't bother reading the readme hard enough to notice if there was any backstory or not.
 
 
 Build quality is kinda dodgy. Architecture is not exactly pretty. Detailing is okhpoh�hf0�8ifm lfpow5
 
 oh fuck this.
 
 
 Riding the robot, which I guess was the gimmick this entire set centers around, was really lame.
 I just couldn't stop thinking about Robie The Robot ( 
http://www.somethingawful.com/cranky/index.php?review=47 ) while this huge, fragile skeleton of shiny metal ass wobbled it's way clumsily at 2mph through the nearest exit.
 I'm not saying I can make a better robot, but if you can't make a better robot than this, don't bother making it.
 Also you don't control the robot as much as you push a button and it walks forwards and you can run around in it's head pushing buttons to make it shoot web.
 
 
 The rest of the levels, I dunno. They're just so mediocre and blah and meh and I think I left a little bit of my brain behind there somewhere.
 I liked the hordes of combine elites for some reason.
 
 
 Tip to the combine robot engineers: put some goddamned armor plating on your robots man, there's fucking huge holes to fire into and murder it's crew!
 
 P.S.: Contains no Barney :(
