Squadmates will die forever if you can't save them
That's not to say that The Bureau is entirely a clone of Mass Effect. It
Battle Focus slows down time and lets you figure out your plan
In the demo I played, I found it unnecessary to ever really fire my own gun; calling The Bureau a "third-person cover shooter" seems wholly inaccurate afterwards. Instead of twitch shooting at enemies, I found myself thinking about how to move my squadmates and ensure they can create effective crossfire opportunities. Concocting power combinations proved to be fun as well. Like in Mass Effect, lift and sniper shot work well together. You can also place mines with one character, and use a different character to use a taunt ability to lure a gray helplessly into the explosive.
While it's clear that The Bureau draws a lot from Mass Effect, it still felt like an XCOM game to me. As an Enemy Unknown enthusiast, I found the transition to playing The Bureau incredibly easy. Sure, it may look drastically different than a turn-based strategy game, but the way you approach enemy encounters remains largely similar--assuming you don't want to lose a single man in your playthrough, of course.
It's certainly been a long journey for The Bureau: XCOM Declassified. And while the game may have strayed very far from its original vision, what it's transformed into today has me eager to play more. As a combination of Mass Effect and classic XCOM, The Bureau could very well become two great tastes mashed into one.
