This is the remake of They Hunger trilogy with new weapons and monster behaviors. The maps remain the same with the exception of new lighting and more defined shadows. There is also "Infection Rate" system which makes it harder to die when on low health, making the gameplay a lot more forgiving.
Feel like there's not enough ammo for the finale of Episode 3 in TH: Relit? Thought that maybe there's a weapon you're missing for that special sauce?...
They Hunger Relit's default M1 Garand Ping is a bit unsatisfying, innit?
