Recover a port engine for the Crozier | 7: Mayhem Dead Space 3 Guide
Last update: 11 May 2016
You'll get information that one of port engines is missing. Once you get to Terra Nova, go right away to the transport ship and travel to C.M.S. Greely.
Once you get to the destination, head to the engine (use locator to locate it). First, use kinesis to remove its metal shields and then pull out three panels.
When you get an access to the engine, pull it out using kinesis.
