Cloakers... Cliffjumper scowled, thinking back of what he knew about cloakers and, instead of turning on his night-vision, just amped up his normal vision, the sensitivity of it. This method wouldn't work in daylight, with a lot of other impressions going on, but it was dark, and there was only the stairwell.

::I didn't think of that... Thought he might have the whole buildin'. Rrr... Could perhaps get security or other guards to take chase if he has the right strings though...:: Cliffjumper muttered over the comm, gun cocked as he peered up the stairwell behind them... or rather, in front of him (since he's turned the other way) and behind Optimus.

His gun suddenly shriek, and Cliffjumper snickers over the comm. Oh yeah, he'd seen those faint, silvery shivers down along cloaked limbs, and while he has no idea what he hit and thus not the damage since he didn't hit the cloaking device itself...
