Looks like Brutal Conflict is a set of scaled-down version of the 40K rules. They also have force rosters with different limitations and point costs.

Good stuff: it's under current development (not abandoned); the rules are similar to 40K; denormalized movement; expanded wound chart; handles small team (2 - 4 models) construction well.

Concerns: different point values means no direct translation from codexes; no "legendary" units (like Wraithlords or dreads) yet.

A lot of the rules clarifications are contained in a forum on Warseer.
