Hello, seeing as I just got four of the hardest achievements I thought I'd share how I did it, and maybe inspire some other pilots to do the same. The four 30+ achievements I'm referring to are Aces Hive, Stingking Hard, Moth-R-Load and War Hero. Infinite Improbability is another 30+ achievement but I don't remember exactly how I did it, I just remember using most of what I did here.

Ram is the pilot I use most, I like his ability that explodes anything he pushes back, so it defends as well as attacks. His attack paired with the Disruptor utility is a pretty devastating symbionic.

The augments I picked kept me in shields, experience and also do damage.
Fave augments include Space Net, Power Converter and Slag Shot.

I tried to pick trials that fit into the flow of how the game works already, without to much disruption to my play style. Trials I used the most where More is More, Debris Field, Many Tanks, The Swarm, Kamikaze, Hunted, Haunted and Bullet Hell.

Feel free to swap trials and Augments to fit your play style.

Gravity Wave & Disruptor evolve to Rupture Wave
Sideline & Feedback Loop evolve to Sideloop
Buzz Beacons & Lightning Rod evolve to light Buzz
Omega Cannon & Recycler evolve to Omega Cycle

I hope this guide helped you out, if so consider giving me thumbs up and checking out my profile with a link to my store. Thanks and have a great day :)
