These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Alien Vs Predator Capcom
Game Breaker: Linn Kurosawa's jumping downward stab/air throw. The stab can hit downed enemies off the ground, and can be done repeatedly while she's still in the air. The Air throw of course knocks enemies down and lifts her a little higher in the air. See a pattern there? A skilled player can jump once, and kill some bosses without her feet touching the ground.
