There is a way to finish the level in about two minutes. Instead of actually fighting your way through the level, jump to the top of the ship that you rode into the station, and onto the "gutters" around the top of the docking bay. Go all the way around, collecting the secret chip on the way. Find one of the "peninsulas" on the ledge on the left side of the docking bay (the one you would have had to use a Loader to get to). You may have to deal with a Scientist on the way to the outside of the station, but you will definitely encounter a shielded Titan. Thus, have an EMP or a lot of ammunition ready. After that, just play through the rest of the level as usual. Do not worry about getting shot at; if you have more than three batteries, you are simply moving too fast to be hit enough to deplete them.
