You have to do this in the Points Count mode, which is unlocked after beating the game once. It isn't too hard, seeing as it is basically the normal difficulty, plus all of your upgrades are already unlocked. You will be able to play each level individually, and if you are missing any monkeys, this would be the time to get them.

If you only are going for this achievement and not 'Target Score Needy!' or 'Target Score Junky!' as well, then the obvious choice would be to beat the easiest level. I would suggest 'Falling for Kafka', as it is a short level and all you really need to do is hold the fire button down to kill everyone.

If you would rather play a different level, here are some tips that will help you reach your goal:

- Please note that the 'Boneyard Workout' level does not count for this achievement. Seeing at it is only a series of challenges and you don't actually accumulate any points, you can only tie the target score, which is 0.

- Never kill enemies while standing still or running. You will only get a measly 1-10 points. Instead, always be in an acrobatic move. I would suggest you not kill any enemies until you are in a second acrobatic move that you stringed together (jump/dive + slide). This will double the points you get for the kill. If you want to go even further you can (wall run + jump + slide), which will boost your points even more. If done correctly, you should be getting 100-175 points per kill, as long as you have a x5 multiplier.

- When entering an arena, go for the multipliers first. Although there are a few exceptions, it is usually best to get a 5x multiplier, before you start killing. That way you will get the most out of your kills, and your average multiplier will net you more bonus points at the end of the arena.

- After each arena, you will get an additional bonus based on your performance. Just follow the tips above and you should get an 'Excellent' in both the average multiplier and acrobatic categories. Don't worry too much about the time category, as you want to stay in the arena for a good amount of time, in order to kill all the enemies. Your overall ranking should be a 'Good' and you'll get an additional 1000-1250 points.

- During the arena fights, don't close any gates until you know there are no more enemies. Enemies will continue to spawn for quite awhile, giving you tons of extra points. Even when you think you have killed everyone, give it a few seconds; sometimes a couple enemies will lag behind.

- If there is a mini-gunner during an arena, don't kill him. Seeing as this is only on normal, you don't really need to worry about health. Instead use him to keep your multiplier from going down. If you are waiting for more enemies to spawn, just keep shooting him. Your multiplier should not decrease, as long as you are shooting an enemy.

- On the car-surfing and free-fall levels, you pretty much have to kill every enemy to beat the target score. During the car-surfing portions, don't worry about headshots. Although it will get you an additional +5 points, chances are, you will miss more and waste precious time. Also, don't forget to use your other weapons. I found the SMG particularly helpful on the motorcyclist.

- On the 'Shock Therapy' level, there are two point pickups that you have to get, if you want to beat the target score. They are both located in the rafters in the beginning area (before the rage sequence). One is located right above the door to the next area, and the other is in the corner above one of the hidden monkeys. Just look towards the ceiling, you should be able to see them.
