True, 4th edition does not expressly say whether or not he informed others about Krell. It does indicate that Bruce was very reluctant to interfere with the timeline. The stopping of the 1989 nuclear war was done reluctantly. After Bruce goes and spends two years in the future after that, he comes back even more resolved to not interfere with the timeline ever again and with the desire to know who Krell is. Given that, I would assume he kept all threat data to himself to avoid contaminating the timeline. How bringing back powerful lasers and portable fusion technology does not do that I will conveniently ignore or assume Bruce saw no significant change in the future as a result of bringing those back.

well back to third edition(i don't have fourth edition yet) in prime base it says that the staff at prime base learned of krell before being wiped out. the fact that his forces were able to secure a nuclear weapon would have pointed to them being a significant threat even if the nuke at the refugee camp was detonated before it could be deployed against morrow in the time between that and the final fall of the base it would have been negligent of the Morrow HQ staff to not send a message warning of this threat before their last stand. add in what i'm being told from fourth edition and there is no feasible way for the the Morrow HQ to have still been in the dark about this threat and fail to send some kind of warning to the teams to be read once they wake up.

Don't buy it until it is revised and properly edited.

well i'm waiting on the modules to be brought up to speed on it as well as the Errata. i don't like having to guess and improvise to make a module work with a new system only to find out halfway through the campaign that they're releasing the module with accurate updates in a week and i did everything wrong.:D

I was really going to pick this up too...cant wait to see the production stuff. Is there a plan to update the 4th book or just a hope?

I would be surprised if there was an update or revision any time soon. It's my feeling that sales have been underwhelming, and that they are likely attributing that to the genre or gaming in general than to any shortcomings of the actual product.

Maybe this should be moved to the Prime Base thread, but rereading the 4th edition rulebook it says that both Prime Base Alpha and Prime Base Beta, for lack of a better way to differentiate Prime Base and the alternate, have an awake staff through the war. This means that at the very least, Prime Base Alpha should have been able to send a message to Prime Base Beta talking about the events in real time, including the nuclear blast. Even if they do not name Krell specifically, Prime Base Beta would know there is a group with the ability to use nukes. This also means that the Project should go on according to plan right at the wars end using Prime Base Beta to awake teams, but that is a discussion for another thread.

Wait... what??? The backup had staff awake during the destruction of Prime Base?? And is still there, frozen?? That makes zero sense to me. What stopped them from waking the Project?

Yup, here is the text, copied from my PDF of the 4th edition:

As a final failsafe, an alternate base was constructed, so that the teams could be revived even if some unforeseen catastrophe overwhelmed Prime Base. This base had the same libraries as Prime, and many of the same facilities, albeit on a rather smaller scale. However, it had only a relatively small frozen staff of specialists in addition to its small “awake team”.

And there is no explanation given for why this alternate base completely failed in its intended design as a failsafe???

this is why i tend to like the idea of software design screwup. it requires less handwavium to cause the Charlie Foxtrot.
