The solution does have a few of errors:
- The previously mentioned key problem. This can be overcome by completing "The Sludge Tank" section earlier in the game as you leave this area with the same keys as you enter it.
- A small section of the solution repeats itslef and so doesn't make sense until you realise the mistake and remove the 5 instructions from the solution.
- The section around "The Hangar" is very hard to complete without full shield so I attempt that section pretty much at the start of the game instead of halfway through as the solution dictates.
- It doesn't tell you what to do with the timebomb or how to escape.
My score: 7450
I've still not completed it yet as I don't know what to do with the bomb. I think you have to take it to "The Generator" or "The Communication Station". Does anyone have a scan of the instructions as I don't remember the actual aim of the game is!
To escape I think you have to leave via "The Teleporter" or "The Black Hole". The exit at "The Communication Station" is no use as there are only 2 'e' keys in the game and you need them to get out of the computer room, which I've not managed yet as I took the bomb to "The Nuclear Power Plant" to see if that worked. It didn't. There must be a section of ceiling in "The Cellar" that you can move through as the solution sends you there after collecting the bomb.
If I complete this I'll probably make a video and post it to youtube, DaveE has done a video review of Plan B 2 and states "it cannot be competed without an infinite energy cheat", I'd quite like to disprove that!
