Once my fury dissipated, I came up with two good reasons for his bizarre and fatal behaviour. Why hadn't he helped me? Why had he damned himself so? This fight was a co-operative one: we had everything to gain by helping each other, and nothing to lose. My last sight was a Phantom assassin coolly running her blade through the Salarian's stomach. Moments later, I furiously shuffled off my mortal Quarian coil. Now, surely, this frog-faced brother-in-arms would come to my aid. The Centurion, eventually, expired, and precious moments of my life yet remained. Still, what was required was beyond obvious - yet he would not do it. I hadn't wired up a mic for this match, so I couldn't scream and beg at him. All he had to do was press one button for a couple of seconds, and I'd be back in the fight, at his side, helping him to win this war and go home with the spoils of victory. Actually, that's a lie, intended to cover my indignity - he was standing right on top of me, feet stomping on my face, taking wild potshots at a Cerberus Centurion hiding behind a nearby wall. My last surviving team-mate, a Salarian Infilitrator, stood right next to me. I've been playing it what might be said to be a little too much over the last week, having taken several characters to level 20 and gotten righteously indignant that I keep unlocking pistols rather than sniper rifles. Jim's done singleplayer, I've done the From Ashes DLC, and now I take on Mass Effect 3's vaguely controversial four players vs AI-controlled enemy waves co-op multiplayer mode.
