I honestly was ready to give this game a 7 or 8, cause while it wasn't perfect, I definitely had fun with the game. But, the last two stages singlehandedly dropped the game to a 6, because they pretty much highlighted all of the biggest problems with the game.
I wish this game didn't suffer through development hell and a rushed release date, because I can see a good game hidden underneath all the janky parts.
The combat can be fun but gets repetitive when you don't have much variety in your moves, especially when a lot of the enemies can only be defeated using a single specific move. The enemies and their designs and movesets are fine on their own, but then the game suddenly throws around 10 of them at the same time, getting hit once can lead you to getting wailed nonstop with no way to defend yourself. The "gore kills" are cool, but do get stale when you have to do the qte's so many times.
The presentation is easily the best part of the game, the reimagined monsters and bosses are fantastic, the soundtrack is fantastic and hypes you up when necessary, and the story was actually a nice touch (aside from the shitty cliffhanger ending lol). Also, Jim Cumming's and Josh Keaton's banter as Rick and the mask is the highlight of the game.
I really hope this series will return one day and give us a proper great beat em up that Splatterhouse rightfully deserves.
