Alien Colony Attack Mission
Alien Colony Assault? Evil!
Don't get hurt, don't get mind controlled, do take it thorough, do throw flares like hot potatoes, do take 30!!!! Don't hand-to-hand Tentaculats, do take 14 soldiers (or more). DO NOT go unless you have Thermic lance and MC knowledge and Disrupter Pulse Launcher, and do edit this post!
The central base structure is the destination, and can be entered via holes created by DPL missiles. These are also very handy for clearing the upper level gallery in this structure.
The types of aliens will differ between phases - although,Tentaculets are more of a problem in low visibility corridors underground. You can profitably succeed in the first phase, and immediately abort the mission in the second, if you want to repeatedly harvest technology from the alien base.
Some of your soldiers will be scattered alone in the second phase.
