Indie Royale's bundles tend to lack the big-name clout of their rivals, but since they're all about "indie" games, that's rather the point. Their latest offering -- The Mixer 3 Bundle -- contains Dark Shadows: Army of Evil, Frozen Hearth, Gateways, Gun Metal, Hamlet, Orborun, Rasternauts and Weird Worlds: Return to Infinite Space, alongside a mystery unlock. I'd personally recommend Weird Worlds as the package highlight: a procedural space adventure that's different every time and over in a few minutes (FTL took a lot of inspiration from it). Perfect to dip into of a lunchtime.
On the flipside, Kiss Ltd sent me a copy of Gun Metal to review, but the ancient original Xbox game hasn't been optimised and won't run on my hardware. Just so you know.
As always, you'll need to beat the dynamic minimum price, which isn't likely to rise much above £2.50.
