A $10 (at time of buying) purchase that focuses on squad tactics, no way near as in depth as main releases but definitely worth the price for the experience. No game breaking bugs (at least for me) encountered in first 5 hours unlike every other release which is a massive improvement, linear story with no replay value (but same case with every other release in the series), lots of fun nods to earlier releases.
Biggest issue is the X-com series as a whole needs to get over the 1 APC/sky ranger & 1 mission/1 day to respond restrictions. I understand you're meant to pick and choose only what you can deal with but it's incredibly contrived - having a full second squad ready to deploy but they're too nervous to hail a cab or call a ride share? You have space for android reinforcements but not squad members? 'Tis silly (in my opinion).
