Hazard Industries was founded in 1990, it was the only testing area in the UK, with all the deadly products Hazard Industries has came up with they lived up to their name now you must go through a set of chambers in Hazard Industries. Good luck!
Redid a chamber from portal 2, kinda restoring it to what it might of looked like before the incident!
If you really have to: you may complain about my lazyness!
