there’s a way to go directly from biome 1 to 3, but it depends on the level layout you get. I wouldn’t recommend it tho. the best way to unlock weapon upgrades is to start at 1 and work your way all the way through each biome.
Nah, if you're going from 1 to 3, you really only need to level up going thru biome 1. Once you've cleared that out enough, you should be good enough to handle biome 3. You don't even have to fight Phrike again either to be leveled up enough.
