A laser rifle

You are a red blooded male, so the choice doesn't take long. You pick the Aurotech RM 275 Battle Rifle. Although you haven't met any large predators yet, you have seen some large tracks. You feel a lot safer with a weapon in your hands. It comes with six battery packs, so you lock and load the first one and are pleased to see the readout: 60.

With your new best friend in hand and enough supplies to last you for a long time, you think it's about time you explore this planet.

You pack enough supplies to last a few days and take off. You travel downriver for half the day when all of a sudden you hear a loud noise.
