Do my bidding
Basically what you want to do is have one or two aquanots with really high scores from the MC labs armed with mc disruptors They dont even have to leave the sub Then have the others go around to look for aliens When you find one use the MC disruptor on them and you have an extra guy for the turn You can have them search rooms and kill other aliens for you just make sure you follow them so they dont leave your site and you can use this tip over and over and over againIts nice to see aliens kill each other
Fatal Bug
Do not interrogate the Tasoth Commander before you have fully researched the advanced crafts Doing so will bring up the final mission but not allow you to develop the aforementioned crafts which are needed to reach the final stage leaving the game impossible to complete
Salvaging a Bad Situation Or Free Tech Advances
Leaving the Commander till last on your research list will ensure a playthrough that can be completed
