These are not the investigations even though this blog has the keywords investigation listed. These are the Briefings or Blue Spheres, the Green Investigation spheres I believe 9 total are spread out over all the Batcave raids. Once again this is what I believe and not know thus why I am searching the internet to help me find the last two that I am missing and how I got to this blog when it will only show you atleast where you can find the last 3 blue spheres that I did not have alreardy. I cannot confirm whether the location of the 4th is correct this I already had that one I did not verify the walk thrus authenticity as to the 4ths correct location or not. I do know that the 3 I was missing were not listed in their correct order, which seems to be consistent of most of the walk thrus for the Briefings and Collections. Many seem to be listed out of order and or have inncorect names to boot, but I will say that with a little extra effort they did make finding my missing pieces much easier to complete, so thank you for that to the origional blogger who uploaded the information from the start.
The Batcave – Inner Sanctum is marked as briefing not investigation!
what a real a$$$…next time do the work yourself
The third briefing shown, is in fact the first, based on the game’s deeds section. However, it should be noted that the first briefing, the one marked third here, is in fact at the very end of the raid, last room, thus should be considered number four…
As for the investigations, simply because they were mentioned (God knows why), Nokes is correct, there are nine… Three spread evenly across all the Batcave raids.. Three in Outter, three in Inner, and the last three in Sub.. Reward: nifty little Technician Goggles..
rewards?
Just a Mark of Distiction
I recommend staying away until I get the nerf I so badly need and am no longer ridiculously overpowered
rewards is 5 Mark of0Triumph USPS3
