head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Pure Mechanics
An explosively destructible run-and-gun starring parody action-movie heroes.

Execution · Practiced Mastery
A top-down co-op shooter testing aim and survival against alien swarms.
Broforce leans Execution (Pure Mechanics); Bunch of Heroes leans Execution (Practiced Mastery).
Broforce leans a little harder on execution, though the gap is small.
Broforce
Run-and-gun reflexes amid constant explosions
Bunch of Heroes
Twin-stick aiming and dodging swarms is the core
Bunch of Heroes leans a little harder on reads, though the gap is small.
Broforce
Enemies are dumb scripts
Bunch of Heroes
Enemies swarm on scripted AI, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Broforce
Random bro assignments and destructible chaos shake runs
Bunch of Heroes
Enemy spawns and waves add some randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Broforce
Knowing each bro's kit and level layouts helps
Bunch of Heroes
Upgrade and co-op positioning choices matter lightly
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.
