With today's game update, the new reserve Val-de-Bois has been released, featuring the alpine reserve, climbing, damage from falling, and the Ibex as new species. They say the Ibex is difficult to hunt, it does not call nor react to callers (so there are none), is very wary, and it often escapes into difficult to reach locations of the map.
They also for the first time ever indicate the size of the now 8 reserves together, setting the mark at approximately 75 km2.
