This will likely be among the first five achievements you will earn, and the other four are just as easy to unlock. Just explore the first few areas, and you will find the items that pop their respective achievements. This one gives you a bomb, which is a bit more powerful than your shield pulse. By pressing X you will drop a bomb on your position. In addition to its use against enemies, you will need to use the bomb to open some passageways and doors. A technique you will want to master is "shooting" a bomb by dropping one, moving slightly away in the opposite direction you want it to "fly" and pressing A to "pulse throw" the bomb. Takes a bit of practice, and aim is not very precise. You will first want to try it on the big black spiders that are blocking your way. Aim for the red spot!
