A rich Chad/bro finds a jacket with smatters of blood on it; he dips his entire left hand in it to be sure... and then his right hand, to be doubly sure.
A suit/bro is unintentionally shot in the leg by his Chad/bro. The bullet wound is gnarly.
An hour into the film a sudden zombie horde descends onto the campgrounds. The one black guy (introduced just a minute ago) dies first and then the suit/bro guy gets feasted on like mice scurrying through pasta.
Some zombies are killed in bloody fashion as well. Mostly by the unjustly vilified Native American camp owner with his dead-aim.
Girl/boss fist fights a hunchback zombie as two guys stand aside and just watch.
In quick succession, three of the remaining survivors each get dogpiled and made into meals.
Of the final two who get away, one discovers he too is beginning to turn and requests that the other shoot and kill him before he does... to which she abides.
