'Halo: Reach' details emerge online?

Screenshots for Bungie's upcoming Halo: Reach have reportedly leaked online.

It is believed that a number of images from the new Halo title were posted on NeoGAF by an internal beta tester, along with a description of the first three levels.

The gameplay is said to be "about the same as the other Halos" and the first stage is apparently set "on a pretty big map". The objective is to find other spartans.

The description continued: "Second stage was pretty action-packed, main goal was to take control of several huge missile guns throughout the map, and provide coverage to a spartan that would hack into the guns and control them.

"Third stage was very similar to Halo's third stage, Truth and Reconciliation. You start with a sniper and cloaking perk, you sneak into an enemy base at night, and you shoot from cliffs."

New weapons are thought to include a Needler Carbine gun, which explodes when three needles are fired at someone, as well as an updated Warthog, which fires volley missiles.

Microsoft responded by saying that it "doesn't comment on rumours or speculation".
