Well, the system didn't melt, so that's good right? We've found a few ways to increase performance which we'll be implementing this week, but overall it looks like the system is solid so we've increased creature spawns (to everything but Raptors, they need some work still) by 500% across the board. Some species you'll find in greater density in some places as opposed to others - For instance Aigathrix prefer steep cliffs and high altitudes, so you'll find them in greatest numbers the higher in elevation you go.
Bring your ammo, check it out and let us know what you think!
