I Didn't Play Birdknights 3 Years Ago...

OD-8: Bird Operators (at time of OD release) only, 4 ops
The original run of Originium Dust happened about half a year before I began playing birdknights (which was shortly after Dossoles Holiday), so I never got the chance to experience the horrors of this event with the bird squad at release. With the rerun, I can at least pretend that I was there 3 years ago, using only the birds available at the time and no modules.
Pretty sure back then I wouldn't have been able to pull off this 4 op clear, but it is (and was) very much possible with what birds had in 2021. Magallan and the snipers are perfect here between their cheap DP cost and swift attacks to handle the slugs, to the point there I think that this is almost as good as it gets for the map. With La Pluma and Magallan's Y module, this is probably 3 ops... but the core of Mag and Archetto will still remain.
