Fantastic game. It controls like RE4 without circle pad pro, like RE6 with it. The game is half survivor horror and half action. You play as up to four different characters throughout the 12 hour campaign, jumping between them. The bulk of the game is played as Jill, with Chris and two brand new characters padding things out. While playing as Chris and the other characters the game throws mobs of enemies at you and enough ammo to level a battlefield... but as stated the bulk of the game is Jill and her scenarios couldn't be more different.
You are always low on ammo, often panicking for herbs and often feel unmatched even with only two enemies on screen, but you're never screwed if you handle the situation smart, even if that means retreating to try and find more supplies somewhere. It is pure intensity and, in my opinion, a perfect example of survival horror. Throw in a dark claustrophobic cruise ship as your setting, eerie and unsettling sound design, monster designs straight out of Amnesia and a few jump scares to boot and I don't hesitate calling it the scariest game in the series, even if it's not that scary compared to many horror titles.
Also interesting tidbit; the man who wrote the game, Dai Sato, wrote the animes Cowboy Bebop, Ghost in the Shell: SAC, Samurai Champloo and Eureka Seven. The story isn't anything special, but yeah.
