ASTRONEER

After trial and error of setting up fireworks in a line hoping to be quick enough to set them off and failing miserably, here is a simple and effective approach to getting this achievement.

Items needed:
Large rover
1 rover seat
10 fireworks
A way of charging rover. (Solar panels or wind turbine)

Set up:
Place 2 fireworks into your top left and right facing backpack slots.
Charge your large rover.
Place 4 fireworks on the front bumper and 4 on the rear bumper
Add your seat to the top.

Achievement time:
Jump into the rover
Press LB and RB to set off all 8 attached
Jump out and press RB and LB to set off the 2 from your backpack.

If all goes to plan and you was fast enough you shall obtain your achievement, if not.. pause the game, click on your save file and click load, upon reload you should be sat in the rover. (Special thanks to kungfustu72 on his input on this solution)

NOTES: Trying to obtain this achievement in multiplayer by setting off 5 each does NOT work. If you want to help a friend once you have got your achievement, reload your previous save and help them.

Happy hunting!

A fun and easy way to unlock this achievement is to use 2 large sensor rings. Each ring has 6 attachment slots that can be activated by going through the ring. Fill the slots on these 2 rings with at least 10 fireworks. Now simply jump through the rings within 10 seconds and you'll unlock the achievement.

For this setup you'll need:

• 2 large sensor rings (2 quartz, 2 zinc)*
• 2 medium platforms A (2 resin, no power required)
• 10 fireworks (10 explosive powder)

For all this, you need to have access to a smelting furnace, chemistry lab, atmospheric condenser and printers. So this will be quite late in the game.
* Note: previously, it was named large storage ring costing 1 aluminum alloy and 2 ceramic each (thanks Sliktor)

A great tip from the guide of death metal jay is that you can make a save before you trigger the fireworks. This way you can retry if somehow it goes wrong or if you want to help your co-op partner.

Thanks to ImprovedPhoenix for helping me prepare for this setup and exploring the rest of the world of Astroneer with me!
I hope this guide was helpful. If something is incorrect or not clear, please leave a comment.

Video of death metal jay's solution. The long wait at the end was the achievement popping. I guess the "game bar" does not record the messages on the PC when recording. However, it did pop for me during this video.
