What players say

87% of 8,025 reviews are positive · 88% of 103 in the last 30 days

Players most often praise the responsive gunplay and Chapter 1's atmosphere and level design. The dominant complaint since Chapter 2's release concerns bullet-sponge enemies, restrictive gas-mask sections, and confusing layouts that players find less balanced and more frustrating than Chapter 1.
