head to head
Neither is simply harder - they are hard in different places. Deceit 2 demands more variance; Rust demands more optimization.

Reads · Bluff & Deduction
Nine players run asylum rituals while two hidden infected sow doubt and pick them off.

Reads · Grand Arena
A multiplayer survival sandbox where human adversaries make every base a target.
Deceit 2 leans Reads (Bluff & Deduction); Rust leans Reads (Grand Arena).
Rust leans clearly harder on execution.
Deceit 2
Some shooting and chases, but softer than the original.
Rust
Aim and recoil control crucial in PvP encounters.
Deceit 2 leans a little harder on reads, though the gap is small.
Deceit 2
Unmasking infected players is pure adaptive human deception.
Rust
Human raiders and roamers adapt to your patterns constantly.
Deceit 2 leans clearly harder on variance.
Deceit 2
Hidden roles, ritual events, and item luck obscure truth.
Rust
Loot and resource spawns add modest randomness.
Rust leans clearly harder on optimization.
Deceit 2
Objectives and tools form a small learnable system.
Rust
Base design, farming, and raid prep dominate strategy.
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
