You'll reprise the role of Commander Shepard (you can port him straight from saves of the first game, if they're still lingering at the back of your hard drive) who, after a rather good opening cutscene, promptly dies, only to be brought back by the pro-human Cerberus organisation (a smart way of keeping continuity despite the skills overhaul). It's then off into the big wide Milky Way to investigate why human colonies are mysteriously disappearing and discover another ancient, hidden threat to the galaxy, all the while building a team of soldiers, researchers and a couple of psychopaths to stand with you in the final, suicidal mission. On paper, then, it doesn't look much different to the first Mass Effect, but Bioware have done just about everything possible to make Mass Effect 2 bigger and better in every aspect.
Now you'll be taking orders from the "Illusive Man", voiced by Martin Sheen. Martin flipping Sheen. It's almost worth a GOTY nomination just because of him.
Back in the first Mass Effect the galaxy we were given to explore was a let down almost as colossal as the game's ambition; it turned out to have precious few planets we could interact with - all but three being practically identical - and reams and reams of text containing the imaginary facts and history of imaginary planets and solar systems, which undermined the supposed "epic scale" that Bioware had promised. This time round, though, the galaxy's scale feels genuinely huge; there are more solar systems to explore with new space stations and cities (before there was only the Citadel), each planet you can travel to looks and feels different to the others, and the planets you can't land on can still be scanned for materials - which can be used to research upgrades - or signals that lead to hidden missions. It's just awesome, the perfect staging ground for any RPG epic, where you can spend hours exploring and barely scratch the surface.
The role-playing itself hasn't seen significant a change, but it has been refined. There are still the same starting classes - Soldier, Adept, Engineer and everything in-between - but there are now fewer starting skills per class (six instead of eight), including a unique, class-specific skill (for example; the Infiltrator can now become invisible). It almost sounds like a step backwards, but each skill now has two branches - let's say you want to level up an enhanced ammo power; you can either choose the branch that allows your entire party to use enhanced weapons, or just have significantly more powerful ammo for a single character. With this system you can build your character and the other party members in specific ways, so that you can not only bring the ideal team to every mission. Plus it helps create brilliant replay value.
As with other RPGs, you'll gain experience and level up by completing missions, and Mass Effect 2's are just excellent. It would have been easy, with the huge galactic scope, for some of the missions in Mass Effect 2 to fade into the background, and feel like little more than mini-excursions for easy cash and quick experience - that's certainly how it was in the first game - but now that just isn't the case. Almost every mission takes you somewhere different, whether it's simply another part of a space station or a whole new world, giving Mass Effect 2 a diversity that most other RPGs just don't have. Thanks largely to flowing cutscenes and the fully-scripted conversations (pretty much every other RPG has you play as Silent Bob's sword-wielding cousin), every mission feels relevant, as if the decisions you make during it could have a proper impact in the galaxy that will come back to hug or haunt you in the next instalment. There's even a chance to go back and read messages from people you've helped in past missions, giving you a sense of personal involvement that is rarely accomplished in games.
But, Mass Effect 2's most improved aspect is the combat. While it's predecessor was let down by the terrible friendly and enemy AI and having to stop the game every five seconds to use abilities via a fiddly radial menu, Mass Effect 2 has none of those problems. The enemy AI is much more advanced; it will try and outflank you, spread out if you're using area effect powers, and even help power up enemies that are in a better position to take you down. Friendlies are much simpler to command - each of your active team is allocated a button on the directional-pad, just tap left or right and they'll move to cover, attack a target or use their power. There are even three hot-keys for your personal powers, which is probably all you'll need now that you only start with six skill trees. All this comes together with a decent, if not a little rudimentary, cover system to create a surprisingly good third-person shooter that is perfectly complimented by the role-playing element.
The new combat system means that playing with Biotics is much smoother. And infinitely more devastating.
The music is still superb and the graphics no longer suffer from the hideous texture pop of the first game, so all things considered there are very few downsides. But Mass Effect 2 isn't perfect; the story - while being one of the better-told video game stories - is still quite short for an RPG, possibly shorter than the first game was, which is a shame considering just how much they have to play with. Obviously with so much else to be getting on with it's not a massive issue - you'll easily be able to get a good 20+ hours out of it without diving in too deep - but it still feels rushed, and could have probably done with one or two more sub-plots to flesh things out that little bit more.But don't let that nitpick put you off, because everything else about Mass Effect 2 is just fantastic. It's a prime example of great video-game storytelling with incredible scope, solid combat and huge replay potential. Game Of The Year? That remains to be seen, but it's definitely a worthy contender and an absolute must-play for sci-fi, shooter and RPG fans alike.
9/10
...the sex scene was better in the first game, though. We don't even see side-boob now. Bloody spoil sports.
