I just cant figure it out as there is no explanation on this anywhere...
do i need more than one laser?
where should they be placed? cause i cant place them in a closed room as it "requires"
and most important does it even work in this version?
i had the same problem.
i found out that for some reason when i started the game it changed my headphones to mic
try looking in your sound manager when you run the game. if its the same problem just change it back to headphones/speakers.
