Where the Wild Things Are

This is actually very very simple and can be done in the village.

Collect plenty of skulls (5 i believe) to unlock the bonus in village that allows you to spawn enemies.

When your in the village go to the section with the falling star surrounded by electricity (or what ever it meant to be) and you will see some rocks.

Press B to go into aim mode and throw rocks at the mound that the 2 electric fly's are buzzing around and it will spawn a lightning bug.

Keep shooting the bug and kill it. shoot the mound to spawn another. Rinse and repeat.

Altho your not in melee combat it still unlocks the cheevo because this is how i did it and i wasnt actually going for this cheevo. i was actually going for the GRASE LIGHTNING cheevo.

A very easy place to do this is in the first act, right after you collect the first star in the game there should be a few beehives. Just stay a little away from the beehives and keep killing the fireflies and as long as you don't hit the beehives themselves they will keep coming out. Just spam RT and it should pop up fairly quickly.

Enemies in this game glow when they are about to attack you. When this happens pull the right trigger to block. Now defeat 15 enemies in a row without being hit to unlock this achievement. This can be spread over several combat sections.

If this is proving to be a struggle then collect all the turtle collectibles and this will allow you to turn on a cheat that makes you defeat all enemies with one hit.
