Look elsewhere, this guide is outdated

@Siepj You can get a fith from the slot machine. @Docco, you have to have 4 powered at the same time.

You can remove the battery from the tutorial pylon as soon as you place it in. There are only 4 batteries as far as I know

i think there is a 5th somewhere you might also be able to get it trough the slot machine if im not mistaken i havent played in a really long time

i put in all the batterys but now it still wants me to put one in the one part of teh actual tutorial, do i have to redo it or is there a 5 battery some where?

I did not have one at all but i restarted the level and it worked fine I am assuming it was just glitched for some reason

As far as i know these on the video are the only ones needed excluding the one you need to do to beat the level, there also should be a slot machine where you can gamble for the battery or do you not have a slot machine at all in your level?

I did all 4 but it still says there is one left? The only one I dont have charged is the acutally tutorial one but theres no 5th battery or slot machine

this video just shows how i have done it but you are free to play in your own way if you find that easier

I found it easier to unlock your 4th pylon in the video first then go for the 3rd last, as I can't win the wave 3rd pylon sends, it's just stupid.
