Darkwalker

Using the Darkwalker
The darkwalker is mounted on spider-like legs, enabling it to travel smoothly over very uneven terrain. The primary beam attack is extremely powerful but changes direction slowly, lagging far behind the crosshair. Thus it is most effective on targets directly in your path or slightly around it. The Darkwalker camera gives you a good view of the map around you - if you see anyone behind or below you, the secondary "yell" attack can knock them off their feet allowing you to turn around and shoot them. The Darkwalker can also crouch, allowing you to pass through low openings and ceilings, and squish anyone who happens to be underneath. A good strategy is to skirt the perimeter of the arena, keeping you back against the wall to minimize the Darkwalker's weakness.

Going against the Darkwalker
While the Darkwalker is extremely powerful, the above combined with its relatively slow movement speed and large size, is also its weak point. The Darkwalker is huge, and slow to move and turn. Especially in free-for-all deathmatch, entering the darkwalker will almost surely cause every other player to gang up on you. Its weaknesses allow players to effectively damage and destroy it by attacking it from behind or running in a large circle around it, attacking in between beam shots. Skilled players should be able to limit the Darkwalker to no more kills than a well placed redeemer if they exploit the Darkwalker's weaknesses.

Team Deathmatch strategy
The Darkwalker's vulnerability is reduced and its firepower increased in team deathmatch games if a second player gets in. The attack of the secondary weapon is much more agile and can help offset the vehicle's weaknesses. The darkwalker is an interesting addition to team deathmatch as it adds an additional cooperative element, making TDM slightly more than just combining the frag counts of several players.
