Soon you find yourself fighting side by side by side with your entire team in unison, all of whom are hurling insults and exchanging friendly banter among the carnage. After the corporation makes an assassination attempt on Shepard, friends from past and present Mass Effect games descend upon it. It employs a few new tricks, such as shield-detonating kamikaze drones and cluster grenades, but mostly it just gets mocked-mercilessly-by you and your squadmates. This new threat is a private military corporation that is, frankly, a less-capable version of Cerberus. Once that is resolved, the second half is strictly person-to-person (or person-to-alien) interactions. The first half deals with Shepard overcoming a dangerous new threat while on shore leave.
In fact, you could almost draw a line down the center of this release. That's not to say this hefty, four-gigabyte update won't offer plenty of combat.
