You cannot replay levels that you have completed. Take your time before progressing or you will miss some achievements! Some areas also prevent backtracking (closing doors). This is especially bad at the end of certain levels. Restart a level if you think you missed anything!

Don't skip ANY collectibles even after restarting a level! This includes User Messages! Having over 100% completion doesn't matter! Collect the items again! I missed 2 achievements because of this.

You need 2 playthroughs to earn the ending achievements UNLESS you create a backup save at the start of the final level (ANTENNA).

Pick up the last fortune cookie.

GOOD FORTUNE (14/14)

Then go further until you find the UNZIPPER's zipping tool. You can zip all processes now including the security guards, but only pick them up if you are going for the DATA-JESUS achievement. Eventually OS9 will give you the anti-gravity tool [G]. There are yellow circles on the ground for most of the places to use the anti-gravity.

You should have x6 zipped items (check inventory with [TAB]) before using the reverse gravity.

Once you go through the next door you will be teleported inside a room. There are 2 processes inside. The CANARY process is immediately after exiting this room and requires using the anti-gravity (see image below).

You can also get SOCIAL MEDIA later by using the DUPLICATE [4] function on the platform to reach him.

You should have x18 items after seeing ALEX again. The last processes in this area are two SOCIAL MEDIAs in the picture above. If you go further you will fall into the 'break room.'

You should have x22 zipped items before going through the next door with ALEX. The last process before going through the door is BANKING.

The last area is the Art Gallery. There's a lot of processes hidden around here. Some are under boxes. As soon as you have x37 zipped processes in your inventory you will earn this achievement. You don't need to make it to the cloud gun or beat the game.

I mostly explain how to get this achievement in the guide. If you just need this one achievement then please read the requirements below. To earn this achievement you need to save all 37 Processes at the end of the game using the cloud gun. You can see which Apps/Processes you missed after completing the game. 19 Processes do not have any requirements and always show up during the final level. All you have to do is zip them and pick them up. The other 18 are missable and require completing some tasks on previous levels before they show up on the final level. They will say 'stayed in the System' if you finished their task but forgot to zip them.

1. BANKING - unloop him during WiFi Post Office level.
2. CACHE CLEANER - tell CACHE CLEANER about UNZIPPER's death during the WiFi's Post Office level.
3. WAT - talk to AIDE PROCESS and purchase the 'Zip File' from the shop during the GPU Art Gallery level. Use the 'Zip File' on the unzipping oven during the Battery Lab level. Give the hearing aid to AIDE PROCESS during the WiFi's Post Office level (WAT NEEDS A NEW NICKNAME).
4. SECURITY GUARD 777 - crush him with the rock during the Art Gallery Corridor level (SOMEONE WILL LOSE THEIR JOB).
5. SOCIAL MEDIA T - beat her dance score during the XOR/NOR Nightclub (HIGH SCORE).
6. PIXEL - give him C0FFEE during the Art Gallery level. You may also need to roll dice during the Art Gallery and User Show.
7. SOCIAL MEDIA I - no requirements
8. SOCIAL MEDIA F - chase him around the XOR/NOR Nightclub until he leaves (near PHOTOS).
9. CANARIES - talk with ALL 5 Canaries in the game. One is on the Data-Sewers level by the water. One is next to the tank of liquid on the Battery Lab level. Two are inside SORTING during the WiFi's Post Office level. The last is near the first cliff a the XOR/NOR Nightclub level.
10. OFFICE WORKER 434 - give him his book during the Resistance Hideout level (NO CLIFFHANGER).
11. PID501 - give him his arm during the Resistance Hideout level.
12. PID101 - pick up HECTOR (orange bit cube) during the Camera's Theater level. Then give HECTOR to PID101 at the end of the Resistance Hideout level.
13. MUSIC&PODCAST - win her rare figurine at the XOR/NOR Nightclub level.
14. RUBBER DUCK & PID404 - pick up the duck during the Resistance Hideout level. Give the duck to PID404 shortly afterwards on the same level.
15. POINTERS & AIDE - free the pointers during the XOR/NOR Nightclub level.
16. FRANK - free his arm from the rock during the Resistance Hideout level.
17. ALEX'S GREEN POINTER - when you answer the phone during the Hallucinations level DO NOT request the pointer be 'put down'!
18. PID123 - when you answer the phone during the DATA-SEWERS level DO NOT suggest harming PID123. Avoid these answers: Poison chips. Unplug charger. Drown in data-water. Just saying 'goodbye' is the best answer.

You might need to give the log to UNZIPPER during the Battery Lab level.
You might need to sort things in SORTING during the WiFi level.
You might need to tell the process sitting on a bench in DIAGNOSTICS/SORTING the answer to #3 is 'The User'.
