I weakened an enemy and then emptied the thing several times and the guy didn't freeze.

But then I couldn't use it (it kills you underwater) but then it is a pointless weapon anyway and only good for rats. Actually I tell a lie, I did find a hidden freeze ray, not very well hidden but I found it. I was looking forward to some platform sections but these are not taxing and there is no scope for exploration as the levels are entirely linear. Even if this wasn't the case the level design is a joke with big sections where you are just walking through corridors with no enemies.

I have never been so angry while playing a game, the frustration from dying and then having to wait an inordinate amount of time to restart is just not forgivable.
