The first release from Nightfall Games since they regained full publishing independence in 2011, Ursa Carrien is a Threat Analysis file -- a self-contained briefing about one particular issue facing the World of Progress.
The eponymous Ursa Carrien are a new stable mutation thrown up by the ever-fluid Carrien DNA pool. They're a strong addition to the species, adding an extra niche -- and an interesting new challenge for the players, particularly ones that think they've seen all there is to see. The briefing is detailed and thorough, and peppered with the quotes and snippets that make SLA Industries so vivid. It includes information on the Ursa's environment, Cannibal Sector 2, along with full background, typical behaviour, origins, combat tactics and full stats. There's also a dangerous little BPN to introduce the Ursa to the PCs. The content, written by RPG veteran James 'Grim' Desborough, is engaging and useful throughout.
As you'd expect from a Nightfall product, the design is gorgeous, and the briefing is peppered with lovely bits of original Dave Allsop artwork. If there's a fault, it's simply that it leaves you wanting more SLA Industries. Still, for 92p you most certainly won't feel cheated -- and other Threat Analysis files are available, with more on the way.
TL,DR: A lovely addition to the SLA Industries canon.
