Hey, in reference to the couple of posts above me, yes, mercenary mode was definitely a great addition to Resident Evil.
-Resident Evil 1 for sega Saturn introduced the first battle mode ever. The Ex. Battle mode for Resident Evil 2 is also super fun, starting from the lab and going back the police station to find the four bombs. Playing as Chris and Ada is cool too.
-Resident Evil 3 Mercenary mode was kinda cool, it had the time factor where the time was counting down and you had to kill enemies to keep it going. And you can only play as Nicholia, Mikhal, and Carlos.
-Code Veronica had a similar mode as well, where you can play as Wesker and Steve.
-Resident Evil Zero had Leech Hunter mode which was super fun.
-Resident Evil 4 was the next level of mercenary game play.
-5 continued and 6 continued that fun,
-But ya cant forget Raid Mode on Revelations 1 and 2.
Revelations 2 Raid Mode was incredible, being able to paly with another player and leveling up tons of characters and obtaining weapons and getting special perks for your guns. I think Raid Mode on Revelations 2 was the best.
Now in reference to Resident Evil 7, I cant freakin wait. The most anticipated game I ever lived through to play. And I lived through em all! I cant explain the psychedness Im feeling. Similar to how Resident Evil 4 changed the pace of the Resident Evil games, I feel 7 is going to deliver as well. Im a fan of all Resident Evil games, everytime I play one, im like, this is my favorite, then I play the next im like this is my favorite. I could play any Resident Evil game anytime and enjoy them all the same, going from the first from 96, all the way to Revelations 2. Theres qualities and aspects of each game that make each one unique.
