Helldivers 2 is locking out players who use older CPUs

Some Helldivers 2 players are reporting that they can no longer play the game on their computers equipped with older CPUs. The issue stems from the developer Arrowhead Game Studios’ and publisher Sony’s requirement that users play on systems that support AVX2 (Advanced Vector Extensions), which has been a feature in many CPUs since 2013. However, the requirement was not properly enforced in the software, allowing some players with older hardware to play the game since it was launched for PC last year.
