If you've played through the new missions and would like to offer some commentary on them, post in this thread. I'll start off.

Security Breach:
Having to worry about something else besides "killing all the enemies" is a nice change of pace. The mission makes decent use of traps and Goggles. One thing I noticed is that the trap and switch placements seem to differ between ranks. I'll have to do more runs to see if that holds true within the same rank. I fear the insta-kill traps near the end will prove to be the undoing of many random parties.

Citadel of Sand:
It is Relics with a new paint scheme and Moatoob enemies. The blocks appear to be fairly straight-forward. The only annoying part is if you have to deal with a Vanda Orga wave that likes to spam Foie.
