Wired but maybe you can get wireless from somewhere.
Would have to go with wireless
yes they can, i have one wired and three wireless and they work together perfectly
NO you can also use wired
You can connect your Xbox by wireless or wired (ethernet).
As long as they are FOR the xBox 360, they should. The wired ones will probably be first to connect because it takes more time for the wireless one to connect. NOTE: I have no experience in this, only for normal xBox 360 controllers (wired and wireless). Hopefully, this helped you guys!
internet a wired adapter (comes with xbox 360) or wireless adapter (I like wireless) electricity
Wireless or Wired (ethernet cable).
No you need XBOX 360 controllers.
There are both wired controllers and wireless controllers. The wireless controllers allow you to be farther away from the Xbox and they also have a dock for recharging your batteries.
if you don't have a wireless connection from the X-box get a connection wire and do it wired
Craigslist
You can get a wireless receiver from Activision support for PS3 and wii. If its for PC or Xbox 360 its wired portals only.
