This looks interesting! Osprey Games posted this pic up on their Facebook page. No info as yet but I'm certainly intrigued!
[edit: added some more info below]
The author has just posted up some more details on his blog here which I've copied and pasted below:
Next up, we have two games published by Osprey, due to hit the shelves in 2016 (announcement here). The first, and the one in the best shape currently, is Broken Legions, a game of fantastical skirmishes in the Roman Empire. The idea behind the game is that the Roman Empire teeters on a gladius-edge, and has sent out hard-bitten bands of legionnaires under the watchful eye of the Frumentarii (Roman secret service) to retrieve occult artefacts of great power. This, they believe, will stop ancient, foreign gods from threatening the supremacy of Rome, and secure Roman rule for a thousand years. Of course, the servants of those ancient gods aren’t best pleased, and so everyone from Egyptian cultists to druidic warbands are out to stop the Romans. There are even secret cults within Rome who believe that dabbling in the affairs of gods is unwise, and so they too oppose the legion.
This is a fantasy skirmish game, which has at its heart a granular D10 system, with a campaign play mode reminiscent of my old Legends of the Old West game. The faction-building rules are pretty freeing, drawing upon a wide range of ancients and fantasy ranges, and it occupies an ‘alternate history’ space, allowing you to field werewolves in your band of Germanic barbarians, and khopesh-wielding mummies with your Settites. Oh, and in some scenarios, you might encounter wandering monsters controlled by a simple ‘AI’ – anything from Minotaurs to flocks of Harpies.
Sounds very much along the lines I was hoping for!
