Huzzah Oni is done!
Now only LNoS, Exodus, NA and PoA. No worries... ha.
Followed RC's run by sprinting past the wraiths and jacking the ghost. Headed towards the gun lakebed and got close enough to get things happening there (including Kat appearing), then headed back to the wraiths, where they'd lost a bit of their menace. Was able to kill one long distance in the ghost without it moving or firing. Then was able to approach the other over the rocket launcher hill for a hijacking without too much hassle. That left me with both locator shots handy for clearing the lakebed quickly, which I didn't end up using as Kat was hard at work when I came back and I could just headshot the elites as she hit them shieldless. Dunno what happened to plasma launcher man, who cares!
Thanks again for the guides, tips and runs guys.
