10 Video Game Rewards For Absolutely Terrible Things

10. Naughty Naughty - Halo 3: ODST

Most alien species in the Halo series are pretty terrible beings. They're ruthless and violent creatures that are bent on destroying humanity at all costs.

However, there are some exceptions to the rule. The engineers of the Covenant, called the Huragok, are an entirely non-violent species that serves its masters as highly efficient supercomputers and expert technicians. They never get in your way, and whenever there is combat happening around them, they ignore it and get on with their work. Some even decide to help humanity at a certain point in Halo's story.

So obviously, you can get an achievement for brutally murdering ten of these floating little guys.

The achievement, appropriately called "Naughty Naughty," appears in Halo 3: ODST. It requires you to kill ten Huragok engineers in New Mombasa, which makes your evil murder spree all the more cruel, as in this particular level, all of the engineers you encounter are either fleeing or getting attacked by hostile aliens.

There really is no excuse for you to take them out. Unless you really think a random achievement is worth the lives of ten helpless alien critters?

You know what? Don't answer that.
