This test may expose you to Cattle Tuberculosis... and Turrets... It is meant to follow the "in between" theme when GlaDOS is just starting to warm up the enrichment center and revamp the chambers. V 1.2 has fixes to two game-breaking bugs.

This co-op map takes you and your friend through the whole facility. You will be testing your cooperative thinking in the clean rooms, in the old section and in the overgrown chamber. Can you think with four portals? Let's find out! Screenshot: http://dl.dropbox.com/u/21031258/Thru-Facility.jpg
