I'm not the only person that edits maps with UTDM-monsters, the original mapper on this had a UTDMT in the center area.
Replaced that with a Cyberus and gave each base their own UTDMS.
The open center area has the most room, as each base is fairly claustrophobic. Which is exacerbated by the UTDMS being armed with ricocheting razor-blades.
Makes for a very fun but tricky little game.
