Kinda a long shot asking here since its an old game but maybe there is still someone active.
We just finished every level in the game except Vault level 17 in the 4 Player mode. We get to the last bit but then the red laser just shoots through the solid wall, making it impossible to finish. Is this a bug or are we missing something? It already really bothers me that 3 achievements cant be obtained since they are bugged but not finishing one single level is another level of sad.
