"Station and Salvation both command a heavy price."
ONI: Sword Base turned out to be more of a grind than a real challenge. Once you clear the initial courtyard, learn how to tango with Elite Ultras, and procure yourself a Wraith, it's almost a walk in the park.
I managed to knock this one out with only 2 failed attempts right away as I got the hang of meleeing the initial Elite to the right. The biggest challenges after that were really just the last 2 camouflaged Elites at the very end. Tricky buggers. I've got WC and ONI:SB in my file share un-rendered (sorry, no bones to spare on luxuries like Bungie Pro) if anyone wants to take a gander. Nothing special, unless if you're into that sort of thing. Some simple tricks in there as per the HBO walkthrough such as using the Gauss against the Hunters and skipping/de-spawning the 2 Generals right before the end. All in all, a great time.
Onward to Nightfall - should be done in about 5 minutes ;)
Oh! 1 more tip - I was having trouble getting Kat to advance and draw out one of the last Ultras right before the Hunters. Not wanting to risk my own frail figure, I pushed her forward by pegging her with the Gauss. Satisfying and productive 8)
