Here are ten TF2 kill clips to make you go "whaaaat," courtesy of CommFT. They've taken the best of all the kill replays submitted to the Extelevision site during December and ordered them according to their awesomeness. The list features some blinding kill streaks, a jammy but spectacular reflected grenade triple-kill, a remarkable string of headshots and a stunning three-rocket juggle kill. The list demonstrates how TF2's calamitous physics can result in some baffling mid-air encounters. Only the very best players can exploit these to earn game-winning ubers and vital kills. It's fantastic to watch.

This Saturday the 28,000 members of this Steam group are planning to play Half-Life 2 together. It's single player, of course, but there's nothing stopping fans from getting together to stroke their chins and nod slowly in mass mutual appreciation for one of the best shooters ever made.

The group hopes that the massive play session will shoot Half-Life 2 up the Steam most-played list and let Valve know how many people are still waiting for Half-Life 2: Episode 3. Valve certainly know this already, and probably receive dozens of emails every day asking "WHERE AM HL3?" but the group hopes to deliver the message in a more appreciative way.

"Instead of focusing efforts in a negative and disrespectful way, we have decided to gain Valve's attention by delivering a basic message: Your oldest and longest running fanbase would like better communication," they say on the Steam group page.

Even if you're not interested in sending Valve a message, any excuse is a good excuse to dip into Half Life 2 again, so why not join in? You can join the Call for Communication to add your weight to their message, or you can boot up and play a little for old times' sake and spend some time with Eli, Alyx and the crew. It's set to kick off at 7PM GMT / 11AM PST this Saturday. Thanks to Brett and Smash for the heads up.

Quantum Conundrum is being developed by Portal creator Kim Swift. It's a first person puzzler in which you play a twelve your old boy lost in his mad scientist uncle's underground laboratory. It's full of safes, switches, lava and vast gaps with no bridges. This would be a serious problem but for the fact that you can switch between five dimensions, each of which affects matter differently. By switching between world on the fly, otherwise immovable objects like safes can be tossed, stacked and even surfed to make it past the mad machines and laserbeams that every mad scientist installs in their homes as standard. It's all demonstrated perfectly in the walkthrough video above from Gametrailers, spotted on RPS. It's out early this year, and looks rather good, don't you think?

Looking for a big new fantasy RPG to play? Kingdoms of Amalur might just fit the bill. A new demo is now available on Steam, giving everyone a chance to dive in and fight the various things that live in artist Todd McFarlene's head. There's a "destiny" system that lets you switch between combat styles in the middle of a ruck, and there should be plenty of mad weapons to mess with. Completing the demo should unlock some bonus items for Mass Effect 3 as well.

Kingdoms of Amalur: Reckoning is available to pre-order now. If you grab it on Steam you'll get some Team Fortress 2 hats. The Origin pre-order comes with nine weapons designed to "give players an edge from the start. It'll be released on February 10, here's a pic of those TF2 hats.

Crysis 2 was the most pirated game last year, with nearly four million illegal downloads according to a report on Torrent Freak. The numbers were collated from stats put out by public BitTorrent trackers, and suggest a slight decrease in overall piracy numbers compared to 2010.

Crysis 2 was released in March, so it's had plenty of time to reach the 3,920,000 downloads mark. Call of Duty: Modern Warfare 3, released in November, was the second most pirated game, with around 3,650,000 illegal downloads. Battlefield 3 was a close third at 3,510,000 downloads. Fifa 12 took fourth place with 3,390,000 downloads. Portal 2 was fifth with 3,240,000.

Those are some rather huge numbers, sadly, and around three times bigger than the most pirated console titles. They're slightly smaller than last year's round-up. It'd be nice if that was the start of a general downward trend, but PC piracy will continue to be a big concern for publishers in the coming year.

With New Year celebrations just around the corner, it's understandable that you might not have time to trawl through our weekly Best Free PC Games archive, analysing every write-up to construct your own top ten list. So, since we understand the importance of ranking free games in order of perceived quality, we've done it for you. Here are PC Gamer's ten favourite freebies of 2011!



10. Don't Take It Personally, Babe, It Just Ain't Your Story

Christine Love. Download it from Christine's website.



With its anime style and graphic novel format, Christine Love's Don't Take It Personally, Babe, It Just Ain't Your Story might not seem like the most enticing prospect to a lot of players. Push past the presentation, though, and you'll find an intricate and notably human story of what it is to be responsible for the lives of a group of teenagers.

You play as a teacher who gets a little too involved in his students' issues. And while the game is only minimally interactive, it does present you with some genuinely affecting moral choices, the likes of which even the biggest videogame developers struggle to get right year after year.

9. The Wager

Surprised Man. Download it from the official website.



An exploration game whose stretches of planet are generated on the fly each time you start, The Wager is a much smarter game than its often primitive presentation would let on. You take to the seas in search of new lands, whose resources you might exploit, or whose co-ordinates you might sell to others eager to spread their feathers into new climes.

It's smart because of the requirement to make decisions about how you'll deal with the game's obstacles, and because of how neatly the often bizarre writing slots into its place in the game. It also received a substantial update recently, making the already compulsive title even more of a delight.

8. Proun

Joost van Dongen. Download it from the official website.



Proun's developer recently revealed that the game's 'pay what you like' sales pitch didn't do as well as he'd hoped. When people treated it as a freebie, though, the response was overwhelmingly positive. It's a gloriously presented indie title that sees you rolling a ball around a frantic racetrack, avoiding obstacles as you go.

Its crowning achievement is the speed at which you travel, and the sense of kinetic energy the game manages to convey. Performing well on the slowest speed setting, 'fast', allows you to unlock unimaginable paces for later races. Let's hope the £23,000 van Dongen did make is enough to convince him to make another game this good.

7. Sweatshop

LittleLoud. Play it on the official website.



Channel 4 gets educational games. Commissioning talented and renowned developers with proven track records, they manage to take concepts that our young could find tedious, and transform them into experiences that even proper grown-ups can get something out of. Sweatshop is one of those games, a title designed to teach of the ills of the horrible forced labour that goes on around the globe.

You play as an aspiring factory manager, hiring, firing and tweaking your factory's workforce. What initially starts as a genuinely amusing title quickly grows dark as your workers begin to tire, you start hiring children for cheaper labour, and you quickly realise you've become the horrific being you promised yourself, at the start, that you wouldn't be.

6. At A Distance

Terry Cavanagh. Download it from the dev's blog.



This is the renowned indie developer's take on co-operative play. Two people sit at separate computers, preferably side-by-side but certainly on a network. Each player is lost in some kind of colourful maze. But it is by exploring the world that the other person inhabits, and seeing what effects your actions are having on your friend's game, that you'll solve the overarching puzzle of At A Distance.

It's clever and inventive, and a shame that the requirement of network play might put some people off one of the more interesting two-player games in recent times.



5. BeGone

NPlay. Play it on NPlay's website.



BeGone has become quite the thing in 2011. Initially launched as a competent and impressive multiplayer shooter, this browser-based gem quickly grew to become something that could rival a lot of full games. There are now several maps, all nicely balanced, and the presentation has been spruced up considerably.

It's a bit like Counter-Strike, basically - and that's hugely impressive, considering this runs in a nice little window right in the middle of a web page. It's a game that requires some decent skill, which it rewards handsomely. And it keeps getting better and better.

4. Stealth Bastard

Curve Studios. Download it from the official website.



A tactical action-platformer, as if Metal Gear Solid were reimagined in true retro-modern style, Stealth Bastard sees you sneaking past robot guards and security systems that aim to take you out in a millisecond. It's fortunate that you can put your sneaky know-how to use across a variety of beautifully imagined levels.

And if those aren't enough, you can even create your own in an initially confusing but eventually fairly sensible level-editing suite that comes free with the already-free game. It's baffling when a developer releases so much of such quality for no coins at all, but it's probably best not to complain too much, or they might stop.

3. Wonderputt

Damp Gnatt. Play it on the dev's website.



One of the most joyously creative games of the year regardless of price, Wonderputt is a crazy golf experience like no other. The game plays out on just a single screen, but it's a landscape that changes radically across the 15-or-so minutes it'll take you to see it all.

That might not sound long, but every second of Wonderputt is remarkable: from the changing landscapes, to the immaculate ball physics, to the splendid music that plays throughout. It's an absolute labour of love, a game that seems to have had layer upon layer of attention gifted unto it throughout the course of its development. 18 holes have never been so delightful.

2. Nous

DigiPen. Download it from the official website.



Nous is creepy. This seemingly sentient AI says it's a psychoanalysis system, but it appears to mean you harm. Or does it? It also enjoys confusing you at every turn as it judges your performance across a series of neon-lit and action-packed levels.

The game's ability to craft such an atmosphere from so little is an extraordinary feat, and it's coupled by engaging game mechanics that see you striking a fine balance between killing your foes and turning them into health by herding them through special converters. It's fantastic fun, gorgeously presented, and both captivating and unsettling as the story plays out.



1. Team Fortress 2

Valve Software. Grab it via Steam.



Well, of course. What else could it be? It's the best multiplayer shooter ever released on the PC, and you can play it for no pennies. We are, quite truly, being spoiled.

We've written about Team Fortress 2 a lot, you may have noticed. Some might say we've praised it to death. Others will be quick to point out its original 2007 release date. But this is the year when TF2 became a free game, and as such it would be barmy not to position it right at the top of the list.

Its quality lies in every aspect of the game. Beautifully and distinctively presented, it's also fantastically balanced, each class playing its own unique role across a variety of maps that, in their immaculate attention to detail and playability, could only have been created by Valve. It's also a game that's filled with personality, as evidenced by the vast amount of fiction that's cropped up around this wonderful shooter.

You get so much for no money at all. It might as well be the full game. In fact, it's not quite, but to upgrade all you need to do is buy a single item from the store. The cheapest item is 29p. That's all you need to pay to unlock a premium account - but if even that seems a bit too much, you'll lose barely anything by playing at the most basic level.

Craig re-reviewed the game this year, upping its original 93% score to a PC Gamer UK 'highest score ever' of 96% as a result of the carefully planned additions and refinements that have trickled in over the years, in what must be one of the most comprehensive post-release support campaigns a developer has ever committed to. We don't give out scores that big lightly - but not only is Team Fortress 2 the best free game in the world, it's also now one of the best in the world regardless of cost.

Found a better free game in 2011? You should totally let us know about it in the comments!

Do you remember the tail end of 2010? We all wore rags and lived in dirt-floored shacks, dinosaurs ruled the Earth, and ‘free to play’ was still a dirty set of words. 2011 saw those words climb into the word shower and wash themselves clean, courtesy of League of Legends.

Developers Riot Games released player figures for their five-on-five Defence of the Ancients interpretation in November 2011. The numbers were, frankly, dazzling. League of Legends now has more active players than World of Warcraft – yes, World of Warcraft – sporting a population of 11 million. More impressively, over four million people play LoL every day, and 1.5 million of those are on at the same time. To put that in context, all of Steam has 2.5 million concurrent users.



But capturing the short term attention spans of children, idiots, and child idiots was easy enough for the terrible free to play titles of the past. Craftily, League of Legends snared their monstrous userbase by bucking that trend, and by being crisp, clear, and blessed with thousands of ways to play. No wonder it’s done so well – it stands out like a golden pin in a shed full of pigswill.

I play as Caitlyn. I stand in the bushes, peppering creeps with shots from my comically oversized sniper rifle. My basic attack is a single shot. My ultimate attack, gained after fifteen minutes of play and souped up over the next half an hour, is a bullet wider than Caitlyn’s waistline that travels a quarter of the length of the map and slams a third out of its target’s health bar. I kill people from a distance, and never let myself near other players.

Tim plays as Leona. She’s a holy paladin, kitted out in gleaming golden armour and armed with a repertoire of incredibly earnest sayings. Leona’s pure tank – she steams into combat, drawing attention and aggression from everyone, leaving other players free to escape or level their weapons on their stunned foes.



Owen plays as Teemo. He runs around behind the AI creep scuffles, watching and waiting for his moment to drop traps. Teemo’s stealthy: he hides in plain sight, supporting his team and sneaking shots against any weakened foes. Well, he’s as stealthy as he can be, at any rate, considering he’s dressed as a fluffy white rabbit, and the traps he lays are easter eggs.

I always play DPS characters. Tim’s tanked for years. Owen… Owen really likes dressing up as fluffy animals. That League of Legends lets us all play different games inside one title is impressive. That it let us play them even when it had one game mode and one map is amazing. That it’s a free to play game with a level of polish, community, and developer support unseen outside of studios like Valve is utterly unheard of.

Highly recommended: Team Fortress 2, World of Tanks.

In most co-operative games, players don’t work together so much as work beside one another. The closest you’ll get to real teamwork is pulling the trigger at the same time. Portal 2 doesn’t work that way. Its co-op problems are impossible without a friend, and each reality-twisting solution forces you to share a brain.

My brain is neurotic, and though he hopefully never noticed, playing with Tom was competitive, too. Every time he worked out the solution first, it stung. Every time my suggested solution turned out to be wrong, I was convinced he thought I was an idiot. The problem is that you’re never just wrong in Portal 2, your idea is stupid, deadly and physically impossible.



Thank god it’s also funny. In singleplayer, Portal 2 is a finely scripted sitcom starring a woman, a robot and a potato. In co-op, it’s a slapstick buddy comedy, with both players as comic foil and GLaDOS as your straight man. When either of us would screw up, Tom and I wouldn’t yell or criticise one another – we left that to Owen and Tim, who were playing at the same time. Instead, we’d laugh, sometimes make P-Body and Atlas high-five, and leave my brain to find reasons to be paranoid on its own.

Having a friend along cancels out all the loneliness you feel in Portal 2's singleplayer. It's a deliberate part of that experience that Chell is isolated amidst the world of test chambers, but it's not always a relaxing way to spend a few hours in the way the co-operative mode can be. Once you've completed both, you're also far more likely to return to the co-op mode a second time than you are the singleplayer. Even knowing the solutions while playing with someone who is on their first run through is fun, as you get to step back and play shepherd to someone else's enjoyment.



As much as acting out the solution is kinetic and wonderful, it was the thought process I enjoyed most. Tom and I would walk in to a new challenge and think: “Um, wait, how do we do this?” We’d both stand still, playing the level through in our mind, once, twice, wait, I’ve got it! If I place a portal here – foont! – and then another here – pshoon! – then I can cover that floor with slime. Then, if I place two new portals at either end – foont! pshoon! – and now you run between them. Woosh. Woosh, woosh, wooshwooshwooshwoosh. And now I place the exit portal here – pshoon! – which will – Wheeeeeeee!

Highly Recommended: Call of Duty: Modern Warfare 3, Fifa 12.

Even though Lego Lord of the Rings has been announced, we reckon they’re fast running out of franchises to render in acrylonitrile butadiene styrene. Lego James Bond is the one we always mention when we see the Traveller’s Tales guys, but so far we’ve had no luck convincing them that squashing a plastic version of Sean Bean with a giant satellite array would be a very good thing.

Flickr user Catsy has completely inspired us to believe that a Lego version of Half-Life would be the way for Lego to go. As Kotaku reported, he/she has created a Lego version of Gordon Freeman using stock Lego bits and bobs, equipped with a customised Overwatch Standard Issue Pulse Rifle made from a Lego tommy gun.

As Catsy notes, Freeman needs a little more smoothing and painting. But between his/her and Orrange Stahl’s attempts at Lego Half-Life, we think there’s more than enough to convince the Danish toy giants to create Lego versions of Freeman, Alyx Vance, The G-Man et al. Who knows, maybe they could even make a game of it.

This is the full length version of the Left 4 Dead fan film that was teased two weeks ago. With Bill's tragic demise, the Left 4 Dead crew are a member short. On the way to a safe room three blocks away they find a replacement. And then another one. And then another, until everything's gone a bit mad. Which one would you pick to become the crew's new fourth member?
