Sunset Heights is around the midpoint of Shadow’s side ofSonic X Shadow Generations, which also means it’s the third to last level and quite a bit more challenging than its predecessors.

It’s not as open-ended as Kingdom Valley, but it’s quite a bit more intense with reaction-time-focused obstacles.

Sonic X Shadow Generations: Every Collection Box Key Location in Rail Canyon

Rail Canyon is a very skill-heavy level in Sonic X Shadow Generations, but luckily, this guide shows you how to find every collectible within it.

That said, this design makes the keys hard to get and occasionally hard to find, so if you’re looking for them, this guide will be your main Park Avenue for nabbing your goodies.

No matter which act or challenge stage you’re on, we’re going over every single key you could want.

Despite Forces' reputation, these stages actually hold many skill-based challenges and alternate pathways that make you explore quite a bit. As one of the final few stages in the game, you’ll have to use most of your skills and explore pretty well to get through it all.

Memory Key

This first key is found after popping out of the first roofed section, on the straightaway, with many cannons and spikes. You’ll find two cannons shooting in opposite directions, one shooting toward you and the other shooting up and away, towards a floating platform with the key. Use Chaos Control when its cannonballs are near the platform, then just homing attack the floating orbs for your prize.

While you’re getting rocks thrown at you by the massive Egg Pawns for the first time, you’ll get a Chaos Control capsule, and you’ll need to use it wisely. Right before the rocks hit the ground, freeze time, then homing attack them to get on an upper platform, where you’ll be rewarded with another key.

If you want this key, you’ll first have to ignore the alternate route on the top left of the sewers, and instead go in the easier bottom right route. Once you kick the Black Arms soldier up into the air, don’t just go straight forward, instead aim upwards for your key and another alternate route.

Despite being in 2D, this act is significantly harder to get with its keys, namely with timing-based challenges that make you either react in time or lose your key. That, or the second key, rewards you for being on the worst path, but we’ll get to that in a bit.

This key is a way into the level after you’ve dodged a bunch of massive Egg Robo Lasers when you’ll be sent over some falling platforms above a river. Quickly jump to the right, and homing attack the line of buzz bombers spawning, then keep chaining those buzz bombers till you get sent right into the key. Alternatively, if you miss your shot, you could just take the lower route, get up high, then go back to the left and boost jump for it.

Immediately after the massive winding rail set piece, you’ll be sent inside, and ensure to take the lower rail for this key. You’ll see it right away, and all you need to do is stomp on the boxes and use Doom Surf to acquire it.

After you’ve gotten out of the sewers, you’ll be sent into a big Egg Robo punching towards the screen. Use Chaos Control to freeze time while its fist is extended, then use Doom Blast to kick it into the distance and grab your key.

Sonic X Shadow Generations: Best Levels Ranked

Sonic X Shadow Generations has quite a few incredible levels throughout both campaigns, and picking favorites is what this list is all about.

Act 1 Challenge 1 (Beware of Spinning Spikes!)

These challenges are somewhat ofa step back from Kingdom Valley, as I don’t think a single one of the keys contained within them is hard to find. However, they are usually at least a little difficult to get to even if you can see them right away, so that’s what I’m here for.

Art Key #1

After getting up the elevator, you’ll be in a small hallway with a few floating platforms. Get to the end of this quickly and hop in the dash ring before the blocks close in around it. This will send you up to the same place you found a key before, you just have to grind the rail in the tunnel for it this time.

Art Key #2

After getting out of the route the previous key takes you on, immediately Chaos Spear a launch pad, then homing attack or boost your way to another key.

While on a slow-moving platform meant to make you dodge spikes, you’ll see a dash ring right above a big wall of spike balls. Jump into that ring, homing attack chain over to your last key.

Act 1 Challenge 2 (One Ring Challenge Lv2)

About 15 seconds in, you’ll see this one in plain sight above a set of spike balls. You’ll need to time your jump so that you don’t get hit by the moving balls of death and not have depth perception fail you, but otherwise, you should know what to do.

Another one in plain sight at the end of the same section, this one requires you to jump across a gap and above a spinning spike trap. Jump for it and be sure to use boost and stomp to save yourself if need be.

Once you’re out in the open, get onto the big moving platform weaving between spike balls, where you’ll see your final key. You can either wait for the platform to move under it, or just jump for it. Either way works.

Act 2 Challenge 1 (Death Egg Robot Panic!)

This first one is in plain sight just a few seconds into the level. Just press the button to the right of it, and then jump down onto the platform to grab it.

Another easily visible one, just press all the buttons on the bottom platform, make sure to avoid the lasers, and jump up to the top left platform for this key.

You can’t miss this one, just play the stage normally, and at the very tail end of the stage, after dodging some lasers, you’ll be sent through rainbow rings that give it to you.

Act 2 Challenge 2 (Dash Ring Rush! Lv2)

Potentially the quickest key to get in this game, you can get this one in 7 seconds by just going through the rings on the ground, then jumping on the upper trail of boost rings instead of the lower.

While you’re using dash rings above a massive pit, just go for the rightmost ring and get another free key.

While you’re flying through the air, you’ll see two dash rings with one on top of the other, and you need to hit the top one. This can be a bit tricky, but if you conserve your double jump and boost you’ll hit it with ease.
