Free games of the week

Zero-K by Zero-K Team

Gaming doesn't have much of a place at the moment for the traditional RTS, which is a shame—every big-budget attempt of the last few years having fizzled out. Indies are still plugging away, however, including developer Zero-K Team, who has just released the not-coincidentally titled Zero-K. It's a traditional RTS! With a single-player campaign and with multiplayer, and it's entirely (wait this can't be right) free of charge. Yep! Reasons you might play Zero-K include its advanced physics system and its nifty terrain deformation, meaning you can build hills or create ditches for tactical reasons.

Post/Capitalism by David Cribb

Rework capitalism into something potentially better with David Cribb's Post/Capitalism, in which creating radical societal change is as simple as clicking on something a couple of times. Don't like capitalism's focus on advertising, and would rather replace that giant billboard with some lovely art? Click-click-click in those changes, my friend. It might be easy, not to mention fun, interacting with the constituent parts of a bustling isometric city, but you don't have the power to alter everything. The city can only handle so much change, so eventually you'll need to pick and choose which parts of capitalism you'd like to keep, and which you'd like to do away with.

Contradiction by Games By Michi

It took me a while to get the pun in the title, but now that I have, I give it a big ol' thumbs up. Contradiction, you see, is pretty much a love letter to Konami's Contra, that delightfully old-school platforming shooter in which oh great I'm already dead. Contradiction inherits its control scheme and its high difficulty level, while bringing in its own, fantastic pixel art, and some physics subtleties that make it feel slightly different to play. I've missed this type of game, and it's great to see the run-'n'-gun shooter making something of a return.

Fanbots by LostTrainDude, Kastchey, CaptainD

Fanbots is an audacious point and click that revolves around a brief Red Dwarf gag. Remember how Kryten's favourite TV show is the Neighbours-style soap opera Androids? Well it's back, baby, or it will be once you've restored it to the airwaves. As one of a team of soap-loving robots, you have to solve odd problems around the TV show's set, with the aim of bringing the unfairly cancelled show back to life. It's an admirably specific and original idea for a short game, and it's realised with great humour and skill, and with an expert knowledge of British sci-fi comedy. (Via Warp Door.)

Hupsi by Tim Garbos, Pernille Sihm, Morten Mygind, Peter Bruun, Anna Stengade, Jesper Taxbøl

Essentially a playable music video that you can tinker with as much or as little as you like, the exquisitely lovely Hupsi is a brief browser or mobile experience designed to be accessible to kids. With its characterful, fluid artwork, and its sweet, organically evolving soundtrack, it's a great game for grown-ups too. As a vaguely Moomin-esque creature runs to the right of the screen, you're able, with the mouse cursor, to prod at items in the background, prodding that always seems to match perfectly with the soaring music.
