As Halo 4's November launch approaches, developer 343 Industries is ramping up trailers for the game, on show at London's Eurogamer Expo this week. The developer's current trend is to focus on weapons from the game; having covered UNSC and Covenant Weapons, the Promethean arsenal closes out the trio.

Weapons shown (below) are the Lightrifle, a medium-range single-shot rifle; the Scattershot, a shotgun equivalent that fires rounds which can bounce off walls; the Suppressor, which seems like a semi-machine gun weapon with its dampened sounds and high fire rate, but relatively weak rounds; the Boltshot, the Promethean version of a pistol, with a secondary fire mode acting like a shotgun; the Incineration Cannon, which is effectively the Fuel Rod Cannon; and finally, the Binary Rifle, a deadly sniper rifle.

Promethean weapons have the effect of incinerating killed enemies from the point hit. For example, a headshot will incinerate a foe from top to bottom.

The Promethean Weapons trailer features seven weapons; adding the human and Covenant previews means 32 weapons are in-game. This contrasts Halo: Combat Evolved's sandbox of five weapons. Players may be interested to see how 343 Industries manages the weapons sandbox. Some weapons may be exclusive to the campaign or tied down to specific gamemodes.

343 Industries recently invited media to its base in Seattle, Washington to preview two missions from Halo 4's campaign, along with Spartan Ops. The reception seems to be mostly positive; a more serious and mysterious tone seems to be the theme of Halo 4. The feeling among some veteran players is it will be difficult for 343 Industries to balance the game across the new weapons, armor abilities, and maps.

Halo 4 will be released on Nov. 6 for Xbox 360.
