Up to 24 enemies on screen before frame-rate is affected in Killzone: Shadow Fall
Guerilla Games has revealed the kind of power that the combination of the PS4's power and their new game engine puts behind Killzone: Shadow Fall.
The game can handle up to 24 enemies on screen before the frame-rate is affected and this is mostly due to the processing of the enemy AI.
“For me as a game designer what I was really interested in was getting more gameplay elements on screen,” explained lead designer Eric Boltjes. “More enemy types at the same time, more weapon types. Bigger areas. For me that gives us a lot more ingredients to play around with. Previously we were limited. You could have six or seven guys on screen, only two types, and it had to be at a specific range”
When asked on the limits of Killzone: Shadow Fall's amount of enemies on screen he stated, “Yes. It’s about 24,” and added, “but that’s just enemy AI. And there are other types of enemy AI, lots of destructibility, lots of dynamic objects. Those have much higher limits but the amount of AI is around 24″.
After that the frame-rate drops due to the fact that each enemy's actions is processed autonomously. He added, “They’re all autonomous, they create their own effects. They’re busy little bees, as soon as you push it over  then we get performance issues”.
Killzone: Shadow Fall is a launch title for the PS4 and will hit the US on November the 15th with the UK and Europe getting it on November 29th.
