Resident Evil 6 is still a couple months away but that hasn't stopped Capcom from revealing the Achievements. The list won't spoil any of the plot but it does reveal a couple interesting gameplay features.
For example, one Achievement tasks you with flying a VTOL (Vertical Take-Off and Landing aircraft) and not damaging it. I found that very entertaining. RE is a series that began with you running away scared from zombie dogs. In contrast, RE6 gives you your own aircraft if only for one segment. I wonder if you get to do strafing runs on zombies, too?
Resident Evil 6 also has some sort of progression system in place. There's talk of purchasing skills and leveling up. You can also earn titles and create custom dog tags for yourself. Sounds like Capcom decided to add a dash of RPG to the game's survival horror and shooter stew.
Like most games, RE6 is seeded with collectibles for perfectionist players to pursue. There are 150 medals to earn throughout the campaign. The Achievements also mention action figures and serpent emblems.
The list below (via Xbox360a) is supplemented by six secret Achievements. Those are the ones with all the spoilers, I presume. I'm going to guess one is awarded for killing Mecha-Albert Wesker during a laser duel on the International Space Station. That sort of ending would not surprise me.
RE6 is due on October 2nd worldwide.
