Breifing: You have just landed on planet SR388. Now you join Jack at the frontlines shooting as a multitude of metroids comes flying at you. Jack tells you that Samus had already gone deep within the metroid nesting grounds, and its your job to continue fire on the metroids until they are gone.
Jack: Die!! *ballistically shoots in all directions*
(Get the idea?)
R-th walks around, and fires five rounds of flaming annihlator into metroid skulls.
R-th: This shouldn't be too hard.
*Jack, after beating R-th for being really horrible, fires a few more rounds at the metroids*
Metroids remaing: 564
R-th jumps in mid-air and fires more flaming annihlator shots at the metroids
metroid count: 498
*samus* this is fun
