I'm trying to unlock Rebeccas nurse costume and have S rank on EVERY mission except from 5-4, I've played it over so many times, but can only get A Rank! Even online I can't get it.... Any tips? Anybody want to play with me to get it? Or in general? If so, send me a PM and I'll send you my friend code.
Ok first of all it's easier if you went solo on this one. I recommend playing as rebecca, due to her explosive gun which helps take out tougher zombies. Equip skill's lucky 7, the one that helps take out stronger enimes and the one that reloads faster or increases your wepon power. Now if you start above, head back toward the time bonus. Now jump down to the center but don't hit the time bonus, use it later. Go the where the chicken is. shoot the chicken and then activate the combo timer. Go out the door and head over toward the coner, stopping to take out as many enimes as you can while the combo timer is still on. Break the time bonus at the coner and continue doing as I told you and head up the ladder. Activate the combo timer if it ran out, as soon as it runs out activate this one. Move down the other ladder break the time bonus and head toward the hallway on the opposite side. Break the time bonus and heres something you need to know. Don't stay in one area. The enimes won't appear if you do. Be sure to turn around every now and then to make sure they won't sneak up on you. Hope this help's. If you do it alone the score requirement for s rank is lower.
