A Challenge

[Landlocked]

In the story missions, I recommend Algol system: Rift for a challenge. Clear all creeper and nullifiables before the timer is up. Sadly, there is no special dialogue or early victory for doing so; it's just for funsies

You're amazing!
It's impossible! Give me a hint!

[Landlocked]

2 things that help a lot: Warp in just above the fortress to shelter from phantoms early game. Involve the main ship in fighting.

Thank you.
In what order did they defeat them?
A：FIXED EMITTER(Top-Right)
B：EMITTER(Bottom-Right)
C：EMITTER(Bottom-Left)
A->B->C?
Have you used "CREEPER EATER LIQUID"? or "IXEIDE"?

[Landlocked]

I didn't use any liquids. I went towards all 3 from the start, but focused B first then got C while still fighting upwards.

Ok I did a replay to make sure I knew what I was talking about.
Start: Erase existing reinforcements, warp in over fort, dig out 2 gems with a minimum of pixilium digging, place generators, open middle tunnel for apex to blast at. Then, move towards right gem with digger, coil, defender, gunship which is enough to subdue the lower right. While that's happening, put all remaining effort into clearing the middle stripe aggressively for gems and map control. Get additional gems as soon as possible. As more ships become available, have a second squad move to the left emitter. Keep the bottom emitters tamped down but most strength is still going to top. You'll be on 2-5 fronts at once, so it's best to pause every 2 seconds to keep them all optimized. Once the bottom emitters are done, use teeny little acid blips to crack the phantoms and clear the rest of the bottom stuff while continuing up top. My best time is 5:15 remaining.

I was playing with the restriction of killing
"ALL Creepers" in each stage,but I got stuck on this stage. hehe
I'll try again and again while taking your play into consideration.
This game series is really fun!
Thank you for the detailed explanation!

I was glad to see that someone else had the same idea of trying to beat this level, only I continued on to see if I could clear the whole map... it took forever because of the rate the creeper multiplies (and because I got overconfident and almost lost a couple of times) but I finally managed it! What helped finish the top section of creeper was putting down a layer of 'creeper eater' liquid near the area I was trying to make progress.
