In episode 2, for one of my save files, I chose to bring Travis back to the camp (instead of the guy in the bear trap). When he turns into a zombie and grabs my face, I start rapidly pressing X (as indicated on the screen), but then, right after Larry or Mark tells me to get out of the way so they can kill him, I keep getting killed. I don't know what I'm doing wrong. I keep trying every button, but I don't get him off me, I just keep dying over and over again. (This happens after I crawl out of the car and land on the ground; he grabs me; I rapidly press X; then after I'm told to get out of the way so I don't get hit with the axe, I can't push him off. What am I supposed to do? I don't know if it's a game bug or if I'm doing something wrong, but it's preventing me from continuing.
