PC, Discovery Channel, free

With plans under way for Discovery Channel to create its own paid-for games for iPhone, PC and consoles, plus two mobile titles already in the pipeline, it’s clear that the TV station is keen to enter the gaming fray. But for those not willing to wait until the release next year of Discovery Trivia, there are plenty of free titles on offer on the channel’s website. The Colony, based on the show currently on air in the US, sees players having to survive in a post-apocalyptic urban environment. Halo it’s not, but as a freebie, it’s pretty neat.
