Ruiner

You can earn this achievement by just finishing the speedrun mode! THERE IS NO MIN TIME REQUIRED FOR THIS ACHIEVEMENT and it'll take about 1-3 hours to complete it depending on your skill level.

The rest of this solution will be composed of tips and tricks that helped me achieve a sub 1 hour time of the speedrun, a requirement to unlock the achievement:
Before attempting the sub 1 hour run, just know that this game will VERY LIKELY CRASH DURING YOUR ATTEMPTS.

I believe there is a way to minimize your crashes by, as ironic as it may sound: slowing down a little bit. It appears that the game loads chunks of the level at a time and if you rush into a section that's not yet loaded then the game will crash and dashboard you (there are NO CHECKPOINTS in the Speedrun mode so that means restarting from the beginning in the event of a crash).

For reference: my best time is 57:06 with a sum of best segments of 53:56. I did this without any Out Of Bounds skips so if you plan on doing any of those I can't help you there. The tips that helped me go sonic fast are below:

1.)If you beat Nerve and then restart the speedrun in the next level you will have the Nerve Sword instead of the pipe for the first 2 levels, this sword will kill all the enemies in the first few areas in one slash. (I didn't do this glitch on my run but it can definitely help shave off a few crucial seconds).

2.)After the 4th encounter in Creep's Nest, pause and buy the Power Slash attack, this shockwave will 1 hit EVERY enemy up except for the bosses and cyborgs. Keep in mind the shockwave does use up energy so you need to manage it wisely. Energy will get used on the chargeup regardless of if you use it or cancel it.

3.)Find a 2-handed weapon for when you are fighting the bosses, the spin attack can get MULTIPLE hits off on the bosses and can finish them off in as quickly as 2 spin attacks after upgrades if you angle it right. This will require a little bit of practice to get the hitboxes lined up right and is always a little finicky in my experiences but still much faster than just shooting them.

4.)Ensure that you pick up the Vis Carver and set it as your dropbox weapon, the damage on it is insane and i've found it to have a more consistent hitbox than any of the other 2-handed weapons.

5.)You can use Overload powered to level 2 to get unlimited sprints (at the cost of energy). This will shave off a few seconds each time you use it but I found it messed with the games' loading mechanic so I ended up not using it on my 57' run.

6.)If you use Electra you can stunlock the final Trafficking boss fight indefinitely and just dropbox a new one each time you're about to run out, this is MUCH safer than trying to kill him with 2 handed spins but is also slower.

7.)With the angel fights, you can two-handed spin to knock out most of it's health and then right before they shoot out the cores, spam the grenade to blow them up in the air, at best I would get all 3 cores and at worst I would still get at least 1 making it easier to dash and get the other ones destroyed.

8.)Disable Ruiner Kills, this will make the waves of enemies appear faster but has a downside of being more dangerous since you can't restock health/energy as often. (You can always pause and enable it in the settings if you desperately need it!)

9.)Pausing stops the timer so use this to your advantage to respec each time you finish a fight to maximize your dashes and vice versa to maximize your lethality in fights.

10.)On mother fights you can spam grenades if you get close enough to her to bring down the health faster. You can also save a few seconds by just tanking damage and dashing through her beam instead of activating your shield to block it but that is obviously riskier.

Here are the times I logged on my run:


Here are the unofficial par times (credit to Zalexzy for finding this and to Vert for making them!)

On Main Menu go to 'Game Modes' to find 'Speedrun'.

The main purpose of this mode is complete the game as fast as you can, which for only this achievement is not completely true.

For this one you only need to beat speedrun, no matter how long the run is, you only need to finish.

After beating the speedrun the achievement will pop. The game is set to NORMAL by default, so, it is not so difficult. You can pause the game or use the menu to check your abilities and the clock will not run, but you actually can't take a lot of time to pause the game or the run will be finished.

On your first try you will roughly need 2 hours. Good Luck.
