Of all, the designers changed to a brand-new entity part system (ECS) design, making parallel execution effective and hence permitting the engine to support a variable quantity of hardware CPU cores. In turn, this allows 'larger, more vibrant and fuller worlds', stated Remedy. Alan Wake 2 is significantly bigger than the very first video game, and Senior Creative Director Sam Lake didn't reject the possibility of moving towards open world-like style in the future.

So-called wind boxes operate like foundation that specify the wind's strength in various locations of the video game, with the objective of accomplishing sensible and differing wind patterns.

The most intriguing brand-new functions are those associated to the upgraded graphics rendering pipeline.
