More news, I asked Chris over at Mantic for a few more details.
Below is his response.
Got to say I am really looking forward to this

'So, some details:
The set contains 10 Corporation Marines and 10 Veer-myn Night-Crawlers (the 8th race, or rats). It also contains a large tile pack, action tokens, and mission counters. The rulebook contains 6 scenarios – 1 training scenario (like a horde mode) and 5 "story" missions.
The game is 2 player, one with the rats and one with the marines, and you take it in turns to play one counter, which can be anything from move and shoot, reaction fire (so shoot when your opponent is making a move), or special abilities like Rush, where 3 rats can swamp a corporation trooper. There's also other counters for ammunition, flares, darkness, hazards etc
It uses a dice mechanic similar to Dwarf Kings Hold, which is our fantasy dungeon crawler. Basically you roll a number of dice equal to your attacks and your opponent rolls their defence (plus or minus any modifiers). You align the dice in descending order (highest to lowest) and for every attack dice higher than your opponent defence, and then higher than their armour stat, they cause a point of damage.
There's more background and what not to the game including why the rats are after the Corporations cargo and why the Corporation are moving the cargo in the first place.'
I will keep you all posted as I get more details
