there's this QTE prompt that will instantly kill a zombie who's grabbing you, but I can't figure out what's the factor to make it appear.
I know breaking crawling zombie grab will always trigger that kick to break their head. standing grab escape does have the instant melee kill prompt too, but it doesn't consistently appear.
the standing grab escape is affected by damage, if a damaged zombie grabs you, there's only a prompt to break their head, no rotating stick involved, but it's also possible to make make the instant kill melee prompt appear for full health zombie. --- Toy Story 4 trailer, best movie 2015? https://www.youtube.com/watch?v=PGuTN_ilmEk
There are only two prompts through escaping a zombie grab that will result in you doing a melee QTE for a possible head critical hit:
When a zombie is laying on the ground and grabs you. When a zombie does a standing grab (not the leap) and grabs you from in front of you.
For the second one, there are two different animations that can happen when you are grabbed like that. You'll know it's the one when it looks like the zombie is just tugging at your arm and you're trying to pull away. --- PSN: Hayato182004 | MHTri Name: H Man | ID: PEECKX | Hunter Rank: 51+ US Server http://www.youtube.com/user/Hayato182004
