Vanquish is one of my all-time favorite games, but I love the controls in RE6 as well. Their controls are similar in terms of how the character turns, and in terms of how you do quite a bit of shooting from the ground (though of course, in Vanquish you slide 40 yards, while in RE6 you slide four feet).
Really, RE6 has great controls, but I didn't understand them right away. In fact, I hated the demo at first. Then I tried it again, on a complete whim (probably out of laziness since it was on the XMB and I didn't want to load the disk for another game).
Here's what I did differently that made the controls click:
- Dial camera sensitivity down from 5 to 2
- Increase aiming sensitivity from 5 to 7
- Switch from crosshairs to laser sight
Now start learning the intricacies of the controls:
- You can throw yourself to the ground with aiming and X, then tap left or right to roll around your opponent on the ground, or up and down to scooch back and forth, throwing off enemy aim and tracking
- Use the above around zombies, or to avoid the sweeping tentacle attacks of transformed J'avo (the non-zombie, mutant-type cannon fodder in this game)
- You can do a running slide by running and then tapping the aim button; while sliding you can do a 180 pivot turn with a twirl of the stick, and/or shoot while sliding at the same time
- You can do a "quick-shot" by depressing both triggers simultaneously; subsequent taps with, say, the Hydra shotgun equipped as Helena makes you do a series of awesome tactical rolls, firing a round after each roll
- You can shoulder-check enemies by running at them and hitting the dedicated melee button, good for tripping up enemies and handling crowd control
- When kicking enemies with melee, be mindful it's governed by a stamina meter so you can't abuse it; circumvent this by stunning enemies to set up context-sensitive melees
- There is also a way to do on-the-fly counter attacks with a strict window of timing, though the trick eludes me at the moment. There is also a way to duck straight under attacks -- I think you just aim and tap X, rather than aiming, X and a direction to leap to the ground on your back.
Once you have the controls down, the "flow" of the game is more about throwing yourself headfirst into each combat situation, save for times when you're up against fortified enemies with turrets and such -- in those cases, slide into cover to avoid the extra step of tapping X to duck behind the wall, and then pick them off from safety. But really, don't play this as a cover-based shooter, for the most part -- like Vanquish, cover is something to use occasionally to get your bearings on a situation, and like Vanquish, sliding into action for up-close combat is key.
