Getting a 40k with Bombermechs took me more tries than I'd like to admit. I cycled through a lot of pilots before I accepted the meta that Bombermechs = Silicamechs, but even then it was rough, because that first island still sees them vastly outgunned. I was even streaming on twitch the night before and griping how there was so much touch and go luck involved in the first few maps - then, I got Silica with +Reactor, and that was just slightly enough of an edge, but I was still failing more often than not - then, I got this run, where virtually everything went perfect, and I got early access to 2 very powerful weapons, Explosive Warp and Frost Beam. Explosive warp gave a much needed push to Swap Mech and Frost Beam took a lot of the pressure off on Island 2, where difficulty peaks IMO. After that hurdled was cleared, you'll see I had pretty much no trouble - and I didn't even upgrade the bomb launcher until the final map because we didn't need it.
Silica is obviously the MVP here, and I tried to make this squad work on Unfair with other pilots, but if you want the 40k he's the best option. The low damage output of the Bomb Dispenser and the lack of damage upgrades on the spiders means it's either blocking emerging vek or taking a hit most of the time, and on Unfair that just isn't enough damage. Silica producing 2 Walking Bombs, or better yet, 1 Walking Bomb and then firing some other weapon, really makes this squad shine. This ended up being my easiest 40k so far, largely due to how smoothly Island 1 went.
