Kira isn’t useless on Underground by any stretch of the imagination. Options are more limited, but you still get to use the orbital laser where it matters most, on the objectives themselves. For instance, if the barriers on Underground are up, you can pretty much block access to the C4 platform by placing the laser in front of the pipe ( slower ) mercs have to jump off to reach the platform. Or just stick it on the C4 itself to prevent defuse/protect a defusing friendly.
Now for something I discovered yesterday: I was up against an Aura camping above the stairs in the building on the left hand side ( from Defenders’ perspective ) on the second objective of Trainyard. She was just popping out and taking potshots at me before retreating into the corner and healing up.
Here’s where it got fun: she was close enough to the corner of the window that placing the laser just outside, hugging the wall, had a large enough AoE to kill her inside. If you encounter any mercs hiding close to walls, try that. Should be helpful if someone’s camping the side building windows on Trainyard, probably elsewhere too.
Not sure if it works if it’s a full wall ( and if so it’s probably unintentional ), but certainly works near doors and windows.
