The 2011 reboot that returned Mortal Kombat to brutal 2D fighting fundamentals.

Reads · Competitive PvP
Minimalist fencing duel that is almost entirely about out-guessing one human.
Mortal Kombat leans Reads (Competitive PvP); Nidhogg leans Reads (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mortal Kombat
Combo execution and punish timing
Nidhogg
Sword-height changes and dive-kicks need quick hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mortal Kombat
Human opponents adapt; conditioning and counter-guessing rule
Nidhogg
Pure human duels of feints and conditioning
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mortal Kombat
Near-deterministic systems
Nidhogg
Symmetric deterministic arenas
Mortal Kombat leans clearly harder on optimization.
Mortal Kombat
Frame data and matchup study converge to known answers
Nidhogg
Small toolkit, little to solve beyond fundamentals
