Laser Blaster

Laser Blaster is an Achievement in Halo 3: ODST. It is awarded for getting 10 kills with a Spartan Laser during the ONI Alpha Site Campaign mission. It is worth 5 Gamerpoints and is quite easy to do because you start off with a Spartan Laser and later in the level there is another one. The achievement can be done at the beginning of the level as there are 3 Wraiths that net you 3 kills each, leaving you with only one kill to get with your last two shots.
