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 okhpohøhf0å8ifm 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 :(
