The most important thing to do before anything else. Set the difficulty to "Normal".



If you set the difficulty to "Easy", none of the achievement will unlock. As for unlocking it on higher difficulty, you can. But at least, make sure that the difficulty is not "Easy".

The next thing is to remember that each achievement must be completed in 1 single try. That means if you have to destroy 9 Planets, you must do it in one go. You can't kill 4 of them at first, then restart and destroy only 5 to get it.

The normal Mode. You gain power-up, kill asteroid and eventually die in the end. With a scaling difficulty, some of the achievements become a bit hard to obtain.

[Celebrity Sniper]

Kill 10 stars in a row [Echoes Mode]
Probably one of the easiest. The star will regularly appear from the beginning and travel across the battlefield. Since they have almost no resistance, you will most likely kill them before you even realize it.



[Blackhole Scum]

Kill 5 black holes [Echoes Mode]
This enemy only appears on and after the level 9. It has the same homing property as the RED asteroid belt, only slower. Quite resistant, it's spawn rate is the only issue, meaning you will be most likely at the level 10 before killing 5 of them.



[Sun Burn]

Shoot the sun 200 times [Echoes Mode]
This enemy only appears on and after the level 10. Fortunately, you will only need to kill 2 of them to get this one. At this point, you shot so many bullets that the 200 times is actually the health of 2 Sun.



[Carbon Footprint]

Destroy 9 planets [Echoes Mode]
This enemy only appears on and after the level 7. Because of appearing earlier than a black hole, it would seem that it will be done earlier too. WRONG! The spawn rate is horrible, with sometimes only 1 planet appearing in an entire level. By the time you destroy 9 of those, you will have most likely all the other killing achievements completed.



[/b]

Get 9999 kills in one game [Echoes Mode]
Just kill them all. Will most likely be unlocked earlier than [Carbon Footprint], to say how bad the spawn rate is.

[Be Strong Big Man]

Score 100k before level 5 [Echoes Mode]
My advice, choose the "Hard/Insane" difficulty. Since it is before level 5, you will only have standard asteroid, big asteroid, the blue comet, the blue meteor and the red asteroid belt. They can overwhelm you, but you will get a lot of score points. It is entirely possible to get it on "Normal", but you will not be allowed to miss too many stars as they are the main sources of multiplier.

[WAIT 6502]

Score over 10k without moving [Echoes Mode]
This is a bit misleading. You could think that you just have to stop moving at any point of the game and earn 10k. No, you have to never move from the start of the game till the achievement pop. You accidentally move a bit, restart.

[Masochistic Tendencies]

Get hit 100 times [Echoes Mode]
Disconnect you pro-gamer brain and allow you to be hit. More likely you will get this by playing a normal game, but it is better to be hit by very small asteroid. They do 1 point of damage and in the early game, you can afford to take damage. Sometimes, you even get the heal powerup by charging head on.

[Run/Stop Restore]

Recover to 100% health from below 50% [Echoes Mode]
Right from the start, try to hit as many asteroid as possible. Prefer the big one that deals more damage. Then, when you are below 50%, get the health powerup and try to avoid being hit.



[Kleptomaniac]

Collect 300 powerups [Echoes Mode]
Gonna catch'em all! Don't necessarily take risk to get them. You will get this most likely near the level 9 or 10. Less if you are better than me.

Even if it seems to be about score, the achievements are more about being good at dodging things.

[Casual Gamer]

Lose less than 10% of your score [Time Attack Mode]
Each time you get hit you loose some score. So, just don't get hit. Most likely, if you aim for Beware of the Leopard, you will get this one as well.

[VIC]

Get a x20 multiplier [Time Attack Mode]
You can gain multiplier by killing the stars and the other asteroid. Because of the time limit, if you see a star, don't let it go.

[Beware of the Leopard]

Take less than 10 hits [Time Attack Mode]
Don't get hit. Good luck!

You have 1 life. Your objective:SURVIVE!

[Stay a While]

Stay alive for 60 seconds [Survivor Mode]
Ha-Ha-Ha-Ha Stayin' Alive, Stayin' Alive
Ha-Ha-Ha-Ha Stayin' Aliveeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

[Live Like the Monk]

Survive for 20 seconds without firing [Survivor Mode]
Strangely easier than one could think. Remove your hand to avoid firing. The first 20 seconds only have the yellow star and blue comet to be careful of.

Double Bubble

Collect a shield powerup [Survivor Mode]
Actually the tricky part. Only 1 enemy drop the shield powerup. It is our friend the blue planet. So, you have to survive and destroy it to obtain the powerup. It looks like that.

After experiencing the turn rate of your ship with a mouse, I can assure you you will feel grateful this is not the main mode of the game. To end a level, you have to destroy every asteroid.

[It Was Better in 2D]

Score over 3333 [Classic Mode]
Survive and kill the aliens to get this.

[The Sauceror]

Shoot 7 flying saucers [Classic Mode]
Shoot the aliens. 1 alien each level meaning you have to survive to level 7 at least. And if you are as bad as me at controlling the ship, it is hard to shoot them.


[We Come in Peace]

Get past level 3 killing no saucers [Classic Mode]
Destroy all asteroid and don't aim at the aliens. You have to enter level 4 to get this achievement.

You liked having homing red missiles faster than Sonic aiming at you? Well, you will be pleased. Destroy them before they destroy you.

[Mind the Edge]

Score 100k without touching the edge [Asteroid Belt Mode]]
You need to not touch the edge of the map. And by that I mean your spaceship. The VERY BIG CIRCLE around your ship is not affected. As long as the blue dot that is your ship doesn't touch the edge, it is fine.

[Lift Out of Order]

Get to level 10 without being hit [Asteroid Belt Mode]
Another don't get hit. Well, don't get hit.

[Snake! SNAAAAAAKE!!!!!]

Get a x5 multiplier [Asteroid Belt Mode]
Hahaha. Funny, isn't it? Like the fact that you need to reach level 32 to get this multiplier. And by that point 5 asteroid belt are imitating Sanic for how fast they can go.

Every few seconds, a line of meteor will appear from one side of the map (the line of blue meteor you see in the Echoes mode). Just destroy a few to not get hit. If you get hit, you loose life and also your multiplier (yellow powerup). You can get them back tho.

[Meteor Maker]

Score over 3 million [Meteor Storm Mode]
A slow and steady game. You just have to make sure to not loose your multiplier otherwise you are here for an hour.

[Zzap!]

Get a x64 multiplier [Meteor Storm Mode]
Destroy the yellow meteor to obtain a new multiplier powerup. It is the yellow one in the image.


[Assassins Greed]

Score 250k dropping no powerups [Meteor Storm Mode]
That means don't get hit. Simple right? Well, just don't get hit is the point of the game so I guess you just have to be extra careful. Also as someone pointed out, you can pick up the Yellow Multiplier. Just don't drop one as you get it. I did it without even the power up and it is SOOOO LONG! So, Kudo to Joestar for being smarter than me :)
