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 · Pure Mechanics
A test of fast, precise shooting and map navigation against scripted but relentless enemies.
Broforce leans Execution (Pure Mechanics); Doom (1993) leans Execution (Pure Mechanics).
Doom (1993) leans a little harder on execution, though the gap is small.
Broforce
Run-and-gun reflexes amid constant explosions
Doom (1993)
Precise movement and shooting against relentless enemy pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Broforce
Enemies are dumb scripts
Doom (1993)
Enemies follow scripted patrol and attack patterns, not adaptive
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
Doom (1993)
Enemy placement is fixed but unknown on first run through levels
Doom (1993) leans a little harder on optimization, though the gap is small.
Broforce
Knowing each bro's kit and level layouts helps
Doom (1993)
Level routing and resource management determine survival efficiency
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.
