peaking round corners is simple.
aim with the ads (default is 'Z') and tilt the nunchuck to the side you wish to lean to. the further you lean the nunchuck the more you lean round the corner and the faster you lean the nunchuck- the faster you lean. then release the zoom to reset or lean nunchuck back if you still want to keep scope on.
another tip for meleeing- that works for me: i sit down to play and play with my arms resting (or nearly resting) on my knees....BUT i keep my left hand (nunchuck) slightly higher.
the reason is because when your hands are level the natural thing to do is raise the nunchuck then swing down.
when your nunchuck hand is higher than the level of your wii-mote hand then a fast downward motion is the natural move- AND ITS EVRR SO SLIGHTLY FASTER....and trust me for a two hit melee kill, that can be a life saver.
must go for now- but when i get time ill give you some more of my personal tips - who knows if they will help you too much but its worth a try.
ooo heres another, this one i have NOT tried, but i have a few ge friends who swear by it.
switch the melee and reload defaults.
assuming you are using the default setting for wii mote play then to reload it is '-' and to melee it is a swing of the nunchuck.
they say to switch them so melee is '-' and swing of nunchuck reloads.
im too set in my ways to try it though lol.
my run and gun 'aim compensation': as you are running around your guy bobs around as you would expect. also holding the trigger and firing off rounds causes the gun to go upwards slightly.
so what do you do?
personally, whilst sprinting around i have my wiimote aimed at a very shallow angle DOWNWARDS. as you bob up and fire a burst you generaly find you will end up hitting centre mass of your target- starting around lower chest height raising to a bullet between the eyes.
works for me anyway
