in the village that captain mitox was stationed, on the far left of the camp (before possesed soldiers) thre is an abandoned house, u have to pick a lock 2 get in. there is another locked door as u walk in (that u cant lock pick) next 2 it is a broken table (not directally next 2 it!) move the package closest to the table there is a key to open the door then u take a chest in there and leave th teleporter pyramid there (when u have the other one) and carry the other one with u (to trasport back whenever)
good idea eh!?
