Chris Redfield runs the RE4 Gauntlet While Nemesis is on his Tail
Chris from RE5 jumps into the world of RE4 and follows the same path as Leon, to save Ashley and beat the crap out of the Los Illuminados and guess what, the Nemesis from RE3 assists the villains in RE4 and chases Chris throughout the entire game. Fortunatley for Chris the Nemesis can only appear in the following areas: The village, outside the church when Ashley gets saved, in the halls in castle salazar (or whatever that castle is called), the mining fields, and finally the location where Salazar was defeated. Nemesis will only appear at that time if Salazar gets destroyed. In that area is the giant laser cannon Jill used on Nemesis. Chris will have to reach it fast because Nemesis will be on his tail and knows how dangerous that cannon is.
Chris can only fight in gameplay and has to face every threat known in RE4 (plus Nemesis). He has all his gear and isn't getting any help from Sheva (it's better that way).
Throughout the game he'll encounter the Merchant, ammo, and herbs. He has all weapons from RE5 minus the laser cannon and he'll have to protect Ashley throughout RE4.
Will Chris survive RE4, defeat the Nemesis, and save Ashley, or will he meet a gruesome end?
