Starting from now and running until Monday morning, the entirety of Rubicon's iOS catalogue will be available to download for free. That includes the Great Little War Game series, plus other titles including Zombies: Dead in 20, Combat Monsters and Fruit Blitz. For the full list of games head to their page on the App Store.
Rubicon's Paul Johnson explained the move in a blogpost: "If you ask a thousand smaller game studios what their biggest challenge is, you'll get the same answer a thousand times - visibility. We're trying a bit of an experiment this weekend, trying to gain some visibility for ourselves. Sales are old hat these days, so we've decided to go one better and just give all our games away, totally free, for this weekend only...This is part experiment, part gamble for us and there's simply no way to know until we try."
