I started writing this story just to point out that Natural Selection 2 is going to have a free weekend over the next few days, and that if you hadn’t yet bought it then you should take a look. It’s a really good indie multiplayer shooter that managed to overshadow Aliens: Colonial Marines in every possible way, and they’ve just updated it with loads of new content. There’s new weapons, female player models, better tutorials, and more. There’s a trailer for that below. But there’s also a trailer for a new crowd-funding scheme as well. Unknown Worlds has released free updates for the game since it’s been launched, but as the game’s returns diminish they need cash to continue working on it full-time. The latest free update cost them $550,000. Their hope? That a tiered donation and reward system will recoup some of that expenditure.(more…)
