Loose script, not needed part two.
I genuinely turned off when at the bridge scene, they dropped 2 robots and then later when they succeeded in fleeing from that scene, they disappeared. All this while the drone was airborne and they couldn't track their escape.
This was another example of loose script movies where some nut director thinks that just because part one was a good one, they need to make part two. Not every film needs a loosely scripted part two.
