Laser Blaster
From Halopedia, the Halo wiki
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 which can be spent on the large clusterd group of brutes and grunts down the bridge.[1]
