The two big changes in the works for the game are a vastly expanded combat engine. Combat was previously a case of Use axe on looter and repeat until someone ran out of HP and collapsed. The combat engine is set to expand to allow the use of a much broader range of skills and manoeuvres based on your characters knowledge and stats. Not many RPGs can offer the option to try and grab an attackers leg and pull him to the ground with you if youve already been knocked flat. Combat wont be decided by Hit Points, but rather blood-loss, shock and other, more realistic incapacitating factors.
The AI seems like its getting an overhaul as well. While mutant monsters might be a little more aggressive, human enemies arent going to want to fight to the death over a handful of berries and scraps that youve picked up in a field, and will often just turn and run if hurt. No more last-man-standing Thunderdome action, which is good. I wonder whether speech-related skills will come into this more later on being able to shout down and intimidate attackers is always an interesting option.
Winning a fight doesnt mean youre going to survive, either. Get slashed with a knife and youre going to be left bleeding with a potentially infected wound, so you need to properly treat the injury. Sterilize rags to use as bandages, take antibiotics to fight infection, painkillers to stop yourself from falling into shock and all that serious medical fun. I reminds me a little of survival-roguelike The Unreal World, or perhaps Silmarils quirky survival simulators Robinsons Requiem and Deus. It might not be the first game to offer a medical system like this, but it makes for a much richer survival challenge.
