Warhammer 40k Dark Heresy's beta flexes the game's murder mystery muscles, but exposes its limits too

With Warhammer behemoths like Dawn of War 4 and Total War 40k sitting on the horizon, sucking in all the attention, it's easy to overlook what a big deal (and a big risk) Warhammer 40,000: Dark Heresy is. Keeping up the high standard of lore-accurate writing and tactical CRPG battling from Rogue Trader is tough enough, but that's honestly the easy bit. The true gamble of Dark Heresy is that it's a detective game that actually makes you do the detective work, lets you get it wrong, and forces you to handle the consequences.
