Time to rock 'n' roll, baby!
Half of these are from my previous run through the cave, but still - sweet satisfaction!
I've earned it!
Although, the offense capabilities are underwhelming, to say the least. Minigun has average damage, but no feats are counted and you're stuck with 15% crit chance. Drill does some good damage, but 25 AP per attack and no MP - yeah, great fun. Rockets are nice, but I do miss half of the time with 90% THC for some reason. You can tank exorbitant amounts of damage and immune to a lot of stuff (TC? Forget about it!), but no stealth, no MP, slow movement speed and constant sound of running motor... It's not indestructible, though - creepy-crawlies from the screenshot above managed to shank more than half of the things' HP. You can't repair it through conventional means.
Frankly, I don't understand why Styg locked it behind one quest from one faction and one location. Make it running from the batteries like jets do, give it limited ammo, allow for repairing it with repair kits - Dreadnought would be a great reward for finishing Protectorate questline. What other RPG can boast mech-combat packed inside?
