How to trigger the optional condition ...

[Kalmatos]

So I completed the game, and I'm going through all the levels to try and complete the optional objectives. Currently unsure how to trigger Dall's optional completion bonus in Ac3, The B Team, Firewall.

What does it mean to have enemies collide with your riot block?

1. I tried blocking the entrance, did not work.
2. I tried charging Dall into the block, also did not work.

Try putting the riot block behind an enemy and pushing them into it. That should do it.

edit: I think pushing the block into an enemy would work too, given the wording, but I didn't think to try that until just now

Your first option works. I sort of tried pushing the block into an enemy, but that didn't seemed like it worked :/
