Scavenger

Using the Scavenger
The Scavenger can move a lot like a player on foot: It can walk, jump and duck, although the latter doesn't make much difference. Additionally it can retract its tentacles and start rolling across the terrain with great speeds. While in ball mode, tentacles can be semi-deployed as deadly blades that spin around the main body. Unlike Scorpion blades, these cannot break off when hitting something hard.

For short-to-medium range attacks, the Scavenger in walk mode can lock on to a target to send out its attack drone. The drone needs to travel to the target first, so this attack doesn't make much sense at long ranges.

It should be noted that players can affect the Scavengers direction while in ball mode by changing their camera view. Skilled players can use this technique to steer without blundering into walls like a gigantic pinball.

The Scavengers drone can also be used to heal damaged nodes.

Going against the Scavenger
A single well-placed AVRiL rocket can easily take out a Scavenger. If you're on foot and don't have the AVRiL, dodging is probably your most efficient weapon against a Scavenger in ball mode, because it's extremely hard to steer in that mode.
