Okay I consider myself an expert of zombies, and zombie info.
If it were during the day RE would ace them easy. Cuz the RE zombies are usually availble to move in daylight. Also consider which RE set RE 1-3 or RE4 and 5? cuz then its RE hands down during the day.
At night though the Dark seekers from IAL are much better than anything RE has, they outnumber, outstrength and well they are just over whelming compared to anything you might see in RE ever.
So day Resident evil
night IAL
If someone keeps me from protecting my friends I will beat them to death...
If they rip off my arms I'll kick them to death...
If they rip off my legs I'll bite them to death...
If they tear off my head I will curse them from the grave.
