Unfortunately the v1 rules are incomplete, and the render the game unplayable.
There is no description of what primer, detonator, combo or multiplier actually mean, mechanically, and the numbers next to the 'systems' in the character sheets are left unexplained.
Additionally 'combo' sometimes replaces 'multiplier' when comparing the character sheets to the main rules.
The shroud has a system that involves 'sacrificing a skill point', that is the only reference to any kind of skill point. This possibly is supposed to refer to an attribute point.
There is a progression system based on earning 'marks', a currency, but the only thing it can be spent on is adding or removing 'tags' from your weapons which feels like a very minor upgrade.
There's a reference to increasing attributes and improving your Aegis when during character creation ("When you make it back, we’ll see about your pay. Tuning up your Aegis, getting new Weapons, hell, maybe even training your Attributes.") but there is no system to do either.
Other than that, I really like the look and feel of the game. The character sheets look great
If these issues are fixed, I think it would be worth the $15. Until then I'd look elsewhere.
