Microbot

The first world comprises of 3 pretty easy levels and then a boss level.

The boss is likely to give you the most hassle, especially with minimal upgrades. I personally found it to be the boss I had to retry on most throughout the game.

Equip your ship with the highest level electron gun you can afford on the front arms and a level 1 carbon rotor on the rear of your ship - dodging and swimming backwards is an essential part to defeating this boss and the rotor comes in real handy.

This boss is all about learning the sequence of the pincer arms whilst shooting its main body. At some point, the boss will attempt to suck you closer, so be prepared and keep your distance for that part. Don't panic and remember you can often get quite close without being at risk from the pincers.

Once you have defeated the boss and progressed to the end of the level, this achievement will unlock.
