An arachnoid is a walking tank, modeled after spiders. They typically have between two and eight legs, making for a stable and maneuverable weapons platform. However, their lack of 'arms' means they cannot use shields for additional defense. Like groundhuggers, arachnoid mechas can make use of turret modules.
+0 MV, +1 TR, +1 Armor. They can mount turrets, but it's better to spend a little time turning to face your opponent than to take a permanent MV penalty. The armor bonus is at the mecha's scale, so it will be +5 armor points per +1 to Armor at SF 1, and +25 armor points per +1 to Armor at SF 2.
