This lock requires you to have a Buddy-Bot on you to open it.
To get one, you have to encounter a special variant on the small robots. Specifically one with a green eye.


When you find one, simply walk up and interact with the little guy. This will place him in one of your free weapon slots. Now that you have a Buddy-Bot, interacting with the lock will open it.

Once you have picked up a Buddy-Bot for the first time, there will always be one available at the start of a run.

Simply arrive before the timer hits 0 and the door will open. This door locks at 3 minutes on the in game timer below the mini-map.

The key to unlock this door is found at the midpoint of the stage "Oasis"

The key to this door is found in the level "Fields", behind the locked door at it's midpoint.



To unlock this door see "The key door in Fields"

The key to this door can be found in the level "Ruins" beyond the laser corridor. Look out for a section of the mini map coloured Orange.


To solve the laser corridor puzzle see the section "The laser corridor in 'Ruins'"

The lasers in the corridor can be shut off by pressing 4 hidden buttons in the immediate area. They are located as follows.

2 are on the roof of the building containing the laser corridor.
1 is on a nearby truck
and the last one is halfway through the tunnel

Alternatively, if you're a g a m e r you can just charge straight through the lasers (with high health of course) or use select class abilities; Namely the Guardian's shield or Recon's teleport. Once the lasers are de-activated they will remain as such upon subsequent visits.

The combination can be found beside the door you took to reach "Ruins"


Just note that this combination is unique to your game, and will be different from that of other players. So using the code from this guide won't work!

The key to this door is sold by Heisen-bot (His actual name) for 9 cells. He begins to appear once you have acquired the Red power crystal. (See "The coloured ticket doors in Haven city - The Red Ticket" for details)

The code for this door can be found at the elemental junction later in the stage. Each time you reach this room an element is chosen and the corresponding door is open. Facing this energy pillar is a window through which a part of the code can be seen. Each element corresponds to a different part of the code. Similarly to the "Ruins" code the combination for your door will be unique; So copying the code in this guide wont work! All 3 parts don't have to be collected in the same run though. Each part will remain static to what ever it is for you.


Notice how you can see the code without even having to unlock the door! Opening it does have its uses however. Such as being able to manually cycle the active element by shooting the small orb with said element. This just requires having unlocked the door, speaking of which...

The key to this door can be found by completing the level "Doom Gardens". To access this stage you must have first unlocked the door in "Fields". Behind that locked door is another one that requires 25 power cells to open, leading to "Doom gardens" After completing the stage you will end up in an alternate entrance to "Aqua station". This one being around the midpoint and containing the key.

The Green ticket


The green ticket can be found in "Waste station". This level can be access by first travelling though "Quarry" until you reach "Aqua station". Once here you will need to take a very well hidden path just before the mid point.



The Red ticket

This ticket can be found in "The pit". To access this level go through "Quarry" until you find the key pad door. Behind it lies the entrance but it is very high up. Be sure to bring a movement tool or two to make the jump. I used the mine launcher to climb the wall but it was super jank. (The mine launcher's explosions give you back your double jump.)


The ticket is found at the end of the stage behind the locked door. The Lock on the door functions the same as the one in "District XIII".


The Blue ticket


This ticket is behind the code door in "Energy centre", See "The combination lock in energy centre" for how to find the code.

This door is located in an orange section of the mini map. It is unlocked by collecting all the power crystals.


This area contains the "Grappling hook" .

To open this door simply defeat the four large enemies in the area (See "The exit door in 'haven square' ") and arrive before the in game timer reaches 22 minutes. This door leads to the area "Harmony square".

To open this door you need to defeat four specific large enemies scattered around the map.
These enemies are visible on the mini-map as a large red dot.

To open this door you must first clear the two challenge areas. These can be found in the purple sections of the mini-map.

Note: The super bot quest can not be completed all in one run and requires the grappling hook. Quest progress will carry over to subsequent runs.

1. Make your way to "harmony square" (See "The timed door in 'haven City' " to access this area). At the beginning of the area turn around and jump onto the second level. There is a hidden alcove there containing "Capitan Mc Slice".




NOTE: Once you have unlocked "Captain Mc Slice" He will be available at the start of subsequent runs.



2. Continue playing through the area, once you reach the end make your way through a hole in the ceiling and collect the "Battery bowtie".



Note: Ensure you have sufficient mobility tools to reach the top as it is quite high up, a single rocket jump wont cut it!

3. Travel to "Aqua station" via "Quarry" (See "The entrance to "Quarry") and reboot Alfred at the midpoint using the "Battery bowtie" and the "Grappling hook". Doing so will give you the "Hero cell" If you have yet to unlock the "Grappling hook" see "The secret door in "Haven city".

Note: that if you have yet to free Alfred from the ice be sure to bring a weapon that does heat damage!


4. Continue through the game until your reach the end of "The moon". On the stairs leading to the final boss you will see a de-activated super bot. Give him the "Hero cell" to re-boot him.


5. After you crush the final boss (or fail miserably :3 ) and return to base camp super bot will be waiting near the "game start" panel. Interact with him to unlock him as a playable character.

I hope this guide helped you out

have a good one!
