    SPOILER WARNING

    This is an unmissable story segment. Once you have destroyed your first Spire, you will be directed to find and destroy a banished AA gun. This is also where the infamous 2020 gameplay demo was shown, so I suggest you stop and appreciate the work they’ve done here since thensmile

    The S bot 9000Note: there's an achievement for finishing this mission within 30 minutes too and since there's no mission select (yet) you'd have to restart the game to have a chance to earn it again if you miss it

    Vum.. it might be a missable achievement as I already completed the story & I didn't pop this one

    I think I just proceeded with the story / skipping this part but clearly the story CAN advance as is the case when you skip certain parts and just progress via checkpoints.

    unless it glitched for me & it is totally unmissabletoast

    TheSierra11705V#5059 its definitely bugged for you. This is an unmissable story segment. You should have gotten it just before you have to fight the 2 boss brothers.

    temprj1234Ugh, bugged for me as well, despite all 3 AA guns and "Pelican Down" being completed and showing as such on the tac map. I even have the "do all 3 in 20 minutes" achievement.

    Unsure how to mark this as buggy, but it definitely should be.
