Well, that was fun, failed on SHIM at December, can't get any live aliens, except Medic, stuck on research 0 implants in stores, Gas weapons require 1-2 shots to kill Gilman, 3-4 to Carcharodon and 3-4 to Hallucinoid. Another problem trajectory, on some missions like Biolab 2nd level you need stay close to enemy due to map design and environment layout. Jet harpoon stun ammo useless, only good against aquatoids. I did NOT get Thermal Tazers too. And of course MC attack is pain in the ass. Incredibly hard. Good luck to all who will try this challenge.
