When you get closer to the Fatboy, the Megalith has a larger DPS rate and will win 1v1 battle vs a Fatboy. Use landscape to get close to a Fatboy with your Megalith so the Fatboy can't fire at you. Thus, you should use your army units (and Cybranasaurus Rexes) to cover them while they attack the enemy army. The Megalith is not powerful but has a high range (64) while the Fatboy II has a higher range (100).Megaliths are good with land units according to the game manual. It's armed with dual laser beam cannons, a large molecular ripper cannon on top, and 4 rear-mounted light AA cannons. The Megalith II Experimental Megabot is an eight-legged Cybran minor experimental land unit.
