There is a problem with the campaign called Plaice holder, which features a lighthouse in the preview picture. After blowing up the enemy in the cage then using the jetpack to get to the shark, then getting to the boat-house, you collect some girders. Upon collecting these, they become the only weapon you have and are automatically selected. You are told that you need to get to the top of the lighthouse. The inside of the lighthouse is completely hollow so you can't climb. You can't climb on the outside of the lighthouse either, since the room at the top overhangs the rest. Presumably, the girders are there to help you up, except as soon as you collect them, you need to place them somewhere. The lighthouse is well out of range, so you have to put them somewhere useless and so you can't get to the top of the lighthouse and finish the campaign, so what the hell is anyone meant to do to finish?

You have to cancel the girder selection.

I have the PS2 version, and I use triangle, which also can be used to select team members. Either that or I press circle, to bring up the weapons panel and choose the skipping rope, so I can move.

backspace on PC iirc

thx 4 the advice
