Sometimes you need a hand to hold, so we ve compiled a list of the 25 best co-op games to play on PC with a headset-wearing friend or a muted stranger.

Whether solving puzzles, sneaking, shooting zombies or stabbing mythical creatures in the face, the existence of another player adds an element of unpredictability. The reality of your co-op partner constantly alerting the guards is drowned out by the experience in your head – the synchronised stealth takedowns, the perfectly executed plan – but both success and failure are more compelling when you can take credit for the former and blame someone else for the latter.

There is a co-op game for every duo and our selection includes a variety of the most bestest. Don t worry if your favourite co-op game doesn t feature – it just means you re wrong. All mortals are, on occasion. … [visit site to read more]

Say, remember when Robert Yang interviewed a load of neat-o level designers while collaborating on a Portal 2 level with them as a sort of playable journalism? I enjoyed the Level With Me series back when I only read RPS, and now I’m here I’m glad I get to post about it.

The first Level With Me creation, made with folks including Brendon Chung, Dan Pinchbeck, Davey Wreden, and Ed Key, had been brokenby a Portal 2 update. Oh no! But this week, Yang released an updated version you can find over here. It’s a fine opportunity to revisit a classic RPS feature.

Industrious internet users at Reddit have dug up brief footage of Valve’s Portal 2 VR demo, the one which was playable at GDC last week and which made me so giddy.

GLaDOS, GLaDOS, oh so monstrous,How does your garden grow?> With portable cells and many dead Chells,And propulsion gel all in a row.>

The original Portal’s Test Chamber 17 is notoriously the level in which the Weighted Companion Cube made its first appearance… and met its fiery doom. Though not before it became the cube with a face that launched a thousand memes.

Thanks to an enterprising level designer, laakkone, that Chamber can now be played in Portal 2. … [visit site to read more]

Have you ever idly wondered whether GLaDOS might have been up to more research and testing than the Portal games let on? A study from Florida State University into the effects of playing Portal 2 on a variety of skills won’t do much to ease your fears, then.

According to the study, spending eight hours playing Portal 2 is more effective at improving a range of cognitive skills than a dedicated brain training program called Lumosity.

In almost every strategy, management or sim game I play, I will immediately turn off the music which comes with the game in favour of my own. That means that Steam Music Player sounds like a good idea to me even if I long ago abandoned mp3s in favour of streaming. The built-in functionality, which lets you browse your music library and control playback from in-game using the Steam overlay, has just left beta after its initial announcement back in February.

To celebrate, Valve have made the soundtracks for some of their games freely available to those who own the associated games, including Half-Life, Half-Life 2 and its Episodes, Portal, Portal 2, and the Dota 2 documentary Free to Play.

Every year Valve hold the Saxxy Awards to encourage and round-up the very best Source Filmmaker creations, and every year the submissions are almost solely set inside the Team Fortress 2 universe. That’s perhaps because they’re Valve’s most expressive characters and because TF2′s manic world is most easily bent towards drama and comedy, but for the just-announced 4th annual Saxxy Awards, Valve are encouraging submissions from other games. Mainly: Portal 2.

A Portal game without portals? “Why, that’s like removing puppies from the Puppy Bowl,” you might say. “What is even the point?” The point, fellow small dog enthusiast, is paint. Physics-affecting paints (think bouncy gel, etc) were part of Portal 2, but they weren’t the main focus. Paid standalone mod/game Aperture Tag: The Paint Gun Testing Initiative puts them front and center, and it looks like sticky, slippery, hundreds-of-feet-in-the-air-hurtling fun. It’s out now, and a trailer’s below.

An oversized revolver, a chunky pump-action shotgun, a bolt-action rifle, and seeing my own legs: the four things I most want to see in first-person games. Perhaps the first three wouldn’t fit too cleanly into Portal 2 but that fourth, yes, certainly! And joy of joys, a new mod has added that very feature, so I spent half an hour this morning running around staring at Chell’s toes as if the mod turned Valve’s puzzle-platformer into Kyphosis Simulator 2014.

I suppose technically the ‘main feature’ in the Thinking with Time Machine mod is a time machine which’ll have you creating time loops to solve puzzles with the aid of your past self, which is great and all but look, LEGS.
