Thoughts on environment "twist"

There's one design choice that really annoys me in most videogames. This happens in good games as well, but usually it is implemented a little differently from the bad ones. I am talking about the environment "twist" that will eventually happen (usually about 60-70 percent of the game walkthrough).

Let's use Bionic Commando as an example of this. This happens in a lot of games but Bionic Commando is still fresh in my mind. During the first half of the game you are gradually given all of your abilities. Some of these include throwing or punching objects from the levels at the enemies with your bionic arm. So you get used to using this method of taking down enemies when you want to preserve ammunition. Boxes, rocks and other stuff like this is scattered around the levels pretty generously at first.

Then at some point you'll start to get in to these "miniboss" fights where you're fighting regular soldiers and 2 or 3 different kinds of biomechas at once. So at first you have the boxes and stuff lying around so you can use them to take the mechas down. But as the game progresses suddenly when you meet these biomechas there just isn't anything to throw at them. This is frustrating as hell. Not because it's overwhelmingly difficult, but because now the game tells me how to play. So I can't choose my tactics anymore because my only option is to duck their attacks and try to attack their backs and wait for some heavy weaponry to drop from the sky in a pod. This feels unfair and it's like the designers are artificially raising the difficulty level. And it just isn't fun when one of your attack tactics gets taken away.

And you really can't even explain these with the environment design or something. This starts to happen in somekind of Harbour and Oil Rig levels. So there really isn't any boxes or other shit in real harbours? And it's really great that the levels are filled with all sort of pipes and ventilators and who knows what but you just can't grab them. I mean really? Why the fuck can't I grab anything small enough and rip it out with my bionic arm and then thrown it against the enemy?

Bottom line, JUST DON'T FUCKING DO THIS EVER AGAIN!
