Blade Kitten

I Think the easiest Level to do this is the first boss-"battle" (Stage 6 - Acland).
Why? Because it LACKS in enemy NUMBERS and is totally PREDICTABLE!

Just do the following and you shoud get this achievment without a single problem:
1.KEEP RUNNING and defeat the four enemys that cross your way. After the fourth jump over the flame pit, defeat anotherone, jump over yet another flame pit and smack down the last enemy in the first part (while running right, duh).
2.Now is one of the harder parts, I´ll call it "ring the bell-stage", where you have to avoid being hit by the Monster and sometimes the sol soldiers. However it´s always the same pattern so eventually you´ll figure it out on your own (or you read through the following^^):
At first he will crush the mid-segment of the floor before you´re even able to move. After that stay put and let him destroy the outer right one. Then run to the very right of the screen (if you´re anxious about getting attacked by soldiers you may have overlooked, you can as well activate your shield. however I made it without it, so it´s up to you and your eyesight). Watch him destroy the top left and following the mid-left section. Sprint to the very left now (but be aware of the sol soldier. it´s self-explanatory but dispose of every one that crosses your path). Stay on guard until he´s crushed the two still left and you´re automatically taken to the next part.
3.RUN to the right. Beat the first soldier, jump over the flames and defeat the next one. You´re now passing what I simply call a "gate" (since you usually activate a checkpoint once you arive at them). However this one won´t activate a checkpoint so keep running. Now simply run down and jump over the flame pit. The main objective is, don´t run into the fire by accident! Keep running and you´ll eventually enter the next and final "ring the bell-stage".
4.Again he´ll start up with the middle, continues with the left and finishes with the right one. After he roars, he´ll crushes the right, then the middle and finally the left one. Plan accordingly and beware of the soldiers, there´s always one in the middle of every section (except the one on top, as he destroys it in the beginnning).
5.The last part is pretty short and easy, but you mustn´t underestimate it, as you go for NO damage after all:
Run right, jump over the two flame pits and pass the "gate". Now be careful as there is a flame pit you have to jump over. Once you passed the second "gate" run to the right, as you don´t wanna get hit by that freak in the end although you´re finished, right?^^ (if you keep sprinting to the very right you might get caught by a floating platform. just make sure to not overuse the sprintbutton and you should be alright)

That´s it. If you managed to clear that level as I told you to, you should own the achievment now.

This mission wasn't that hard to complete and was pretty fun. I made a guide for it last year using Windows Movie Maker and Black Magic Intensity.

Play this on level 6, which is the level with the giant godzilla-zoidberg monster in the background.

1st section:
Keep moving right, pressing X rapidly as you do to kill four enemies on your way.

After 4th enemy, get ready to jump over a flame pit, and kill another enemy as you land by rapidly pressing X.

Jump over another flame pit and kill the last enemy.


2nd section - in the list below, the position you want to be in is on the left. The position the giant enemy attacks is on the right:
left - middle
left - right
right - left
right (guarding) - roar
right - left
left (guarding) - right
left (guarding) - right


3rd section:
Keep running to the right. Kill the first soldier, jump over the flames, and kill the second soldier.

You'll go through a tall structure. Jump over the flame pit.

Keep running and you'll get into the 4th section.


4th section - in the list below, the position you want to be in is on the left. The position the giant enemy attacks is on the right:
left - middle
right - left
left - right
left (guarding) - roar
left - right
left - middle
right - left


5th section:
Run right, jump over the two flame pits and pass the "gate".

Be warned, when you go through the tall structure, there's a very large flame pit you need to jump across. You'll may need to sprint jump for this, but I believe it's possible to double jump over it.

Keep running right.

After the cut scenes have finished (press B to skip), achievement unlocked.

Complete any mission without getting hurt, the best missions to do this on, is either the second mission or the last mission, as they are the quickest and easiest missions to complete.
If you think that you are about to be hit in the mission, hold down the Left Trigger (LT) and your shield will activate.
