Completed my 86th Mission / 23rd Completion Tier and was awarded the Krionite Transducer as expected. I assumed the wiki was out of date but just as it warned "Currently this is as far as you can get with mission finish rewards. More will be added over time." the mission tier award bar has now disappeared from my missions tab. The wiki has contained this warning as long as I have been playing so no new awards have been added over time.

With around 30 missions remaining there is certainly room for a few more Completion Tier Awards, even if they started taking 8 or 12 missions instead of 4 to unlock after the 86th one. I felt they were a great incentive to do missions beyond the mission reward itself. Anyone who feels the same should provide their own suggestions for the next award incentives and anyone who has long ago surpassed the mission counts should be awarded them automatically once they become available.

Example for discussion:
90 Missions Ended - 24th Tier
Superstring Manifold: A powerful structural enhancement which allows some equipment to extend into other dimensions. Increases ship size 2%.

Thanks Dan for a great game!

wow! id do missions like crazy JUST for that 2% bonus.

Yeah, I mentioned this awhile ago too. I got the last reward and didn't even complete all the useful missions, much less the boring ones (I still have Capture Cargo Ship, Research Espionage, and Dangerous Rescue, for example).
