2. Child of Eden General hints and tips

Glossary

Octa-Lock / Perfect Octa-Lock - A fully charged shot from the lock-on laser (A button), releasing it to the beat of the music makes it perfect and ups the multiplier. The two terms are used interchangeably, as if you have an octa-lock, you should always go for the beat.

Tracer: RT releases a rapid fire laser. This is used to shoot down projectiles and weaken certain enemies. If they're purple, tracer.

Euphoria: Bombs. Hit the B button to clear everything on the screen. Generally you won't want to do this, as mentioned in scoring strategies below.

Scoring Strategies

The five star cutoff is rated at 800k points for every archive. The key to hitting these marks is to not simply shoot everything on screen, but to consistently achieve perfect octa-locks. To achieve a perfect octa-lock, you will have to acquire 8 targets and then release it in time with the beat. I find this much easier to do with the controller than trying to time a wrist flick on the Kinect. While I've heard that the controller vibrates in time to the beat, frankly, I never noticed it in 20 hours of game time. If you're having trouble keeping with the beat on scoring runs, go into the options menu and turn the sound effects down to nothing or almost nothing - you'd be amazed how much of the music gets drowned out by the other sounds of the game.

The multiplier, which goes up to x8, is the most critical aspect of scoring high. However, the multiplier only activates on an octalock. Firing at less than eight targets will not cause you to lose your multiplier. If you are slightly off-beat and score a "good" rating, your multiplier remains intact. The only way to lose your multiplier is to fire an octalock completely off beat, so if you have eight targets, make sure you fire on time, even if bullets are coming at you.

Furthermore, knowing the levels is just as critical as octalocking to scoring high. Going for every octalock will result in losing your 100% purification; you'll need to know when to go for octalocks and when to start spamming the A button to quickly take things out. In the gold star videos, I will point out when you want to octalock and when you want to spam, and in some cases, like Beauty, how many Octalocks you can get off before switching strategies.

All were not created equal in this game; not everything will give you points. For example, the gateways and the lotus petals are not worth points, so attempting to perfect octalock them is a risk for nothing. The only reason you would want to is to if you lost your multiplier and need to get it back quickly. Conversely, schools of fish like in Matrix and Evolution can be locked onto and if you are fast you can score points off of these, despite the fact they don't count for purification.

Lastly, you will get a 100k Euphoria bonus for finishing the level with all 3 euphoria unused. It is important to learn which enemies drop them (2 per archive) and trying not to use them. You get 100k for 3, 50k for 2 and only 25k if you have one. This is a major part in scoring high as it means that you will only have to finish with 700k if you can consistently get all 3 euphorias. On later Hard levels, aim for 750k to give yourself some wiggle room to use a euphoria.

Gold Star Strategies

Acquiring a gold star is very challenging and in some ways requires a different mindset. The key is to balance killing enemies quick enough before they go offscreen for the 100%, and still killing them with perfect octa locks to hit the score target. While balancing, the most important thing is that if you drop below 100% in an area, you've lost the gold star, so there are sections where octalocks are not feasible and you'll need to spam. Knowing how much time you have to kill certain enemies is key. Go for the 100% first and foremost, the 800k tends to come from preserving your multiplier.

Turbo Controllers

A turbo controller will make Hope and 100% purification far simpler, but others will be made much more difficult. For 100% purification, a turbo controller will help in almost all respects and make it much easier. The exception is whenever one enemy spawns more enemies, like the pods in Beauty that spawn enemies one at a time. If these are purified too quickly, the 100% is lost; having done these achievements with a turbo controller, I found I was more likely to accidentally fire on them while turboing.

However, it is altogether useless for stars. As mentioned above, the five star cutoff is 800k points, with a gold star being awarded for 100% purification on top of that. The vast majority of points will be obtained through octalocks, which you simply won't get with a turbo controller. For that reason, the guide has been written as a gold star guide and will assume you don't have turbo capabilities.
