A zombie survival sim where long-term planning outweighs moment-to-moment skill.
Soulstone Survivors
Optimization · Systems & Chaos
Skill-active survivors-like with curse stacking and boss-rush escalation.

Axis by axis
Execution3 vs 4
Soulstone Survivors leans a little harder on execution, though the gap is small.
Project Zomboid
Combat is deliberate; precision matters but is slow.
Soulstone Survivors
Active skills and dodging beyond auto-attack.
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Project Zomboid
Zombies follow scripted behaviour; no adaptation.
Soulstone Survivors
Scripted enemy waves.
Variance5 vs 6
Soulstone Survivors leans a little harder on variance, though the gap is small.
Project Zomboid
Loot spawns and zombie distributions randomized.
Soulstone Survivors
Skill and curse drops swing builds.
Optimization8 vs 8
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Project Zomboid
Skill grinding, base setup, and routing define survival.
Soulstone Survivors
Curses and build crafting reward planning.
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.
