head to head
H1Z1 asks more than Worms 2, and the gap is variance.

Execution · Grand Arena
Early battle royale where scavenged loot and shrinking gas decide 150-player brawls.

Execution · Competitive PvP
Turn-based artillery comedy where teams of worms annihilate each other.
H1Z1 leans Execution (Grand Arena); Worms 2 leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
H1Z1
Gunfights and vehicle control decide duels
Worms 2
Ninja rope mastery and pixel-perfect grenade arcs win games.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
H1Z1
Outguessing human rotations and pushes
Worms 2
Human opponents bait positions and hide intentions.
H1Z1 leans clearly harder on variance.
H1Z1
Loot spawns and gas circles randomise runs
Worms 2
Wind, crate drops and terrain randomness swing turns.
Worms 2 leans a little harder on optimization, though the gap is small.
H1Z1
Drop spots, loot routes, and zone play
Worms 2
Weapon economy and positioning theory are studyable.
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.
