Fusion for Dummies - Big Oil Day 2 Engine Calculator
By compassghost
A calculator to assist in the determination of the correct fusion engine to select based on intel collected. Also helps with determining contents of a pre-packed bag.
Calculator Link and Instructions
Fusion for Dummies[]

Go to the link above and use the radio buttons to find out the appropriate engine.

The calculator indicates both the location of the engine, and its number in packed bag form, so if you or someone has already packed a bag incorrectly or accidentally.
Worst Case Scenario: The 50/50 Distributions
The following distributions create a rare 50/50 chance where two tanks match the information. Based on user observations, the following appear to both meet the requirements. There is a 50/50 chance that you will get it correct due to both of the tanks being equal. Take both, and hope your first one is right.

  • 2 Tubes, Helium, Greater Than or Equal (#3 or #6)
  • 3 Tubes, Helium, Less Than or Equal (#7 or #10)
Kudos for the info provided by Insert_Sex_Here @ Reddit and the original images on Imgur[] by REACHGROUND.

I wrote this applet myself using basic JavaScript. Feel free to examine the source code if you wish, and attribute if you use it for your own work.

Your guide is really interesting. I'm thinking about adding it to the BankOfGuides group.
Your name will be mentionned below your guide, so you can get full credit for it.
Feel free to tell me if anything's wrong with that ;)

Greatest guide in PD2 since the game went out. I don't really get why people still make more guides with poor pictures of the room when we already have an animation that works perfectly fine since one year..

I assume you work backwards. As long as you don't have the 50/50 choice, you just throw all the bags but the correct one on the helicopter.
