boring and unoriginal
Well, I'm sure this wasn't easy to make, so that's why you have any points at all. The controls are lousy. The character turns too slowly and she never seems to shoot in the right spot (but interacting with switches works fine, even if the animation doesn't match). The enemies look like low-poly Predator models and the hands of the woman in the first scene are hideous. I know your poly count is limited, being a 3d modeler myself, but you could have done better (and been more original). The dialog in that sequence is awful. Pleading with a grunt to "save the planet"? That just sounds ridiculous, like from a Captain Planet re-run.
Which brings me to the plot itself. Do you know what a "stock character" is? According to dictionary.com, a stock character is "a character in literature, theater, or film of a type quickly recognized and accepted by the reader or viewer and requiring no development by the writer."
The most common stock villains in America today are businessmen. Common stock heroes are journalists, environmentalists, and 'peace' advocates/ protesters (I'm not really sure of the order of prominence at this time). Robin Hood types are also making a comeback.
I must admit, it was pretty original to make the protagonist a lesbian, but the evil energy company thing is just way too overdone to interest me. These kinds of stories also put me off because it seems that the companies that hold up the weight of the world are being unfairly vilified. Granted, this is a Sci Fi thing and you probably weren't even considering big business in general when you made this, but it all seems to follow the same premises:
Businessmen want to control society.
All big businesses cheat and exploit their workers and customers.
Competition is cruel.
Big businesses=bad, small business=good (until they make too much money).
Money is the root of all evil.
I'll spare you any speeches on the moral and economic justification for laissez faire, but I will tell you that nothing big business (even energy compaies) have done justifies the image they have today in the media.
Bottom line: The story is unoriginal, the models look bad (and unoriginal), and the controls are awful.
Would you rather I just said "this is awful" and gave you a zero? At least now, if you want to tell me off, you be more detailed than " * you!".
Okay, I'm done.
