Factory is a neutral alignmenttown with the mercenary and artificerhero classes. Factory armies combine nature with an attempt to harness its power, featuring humans wielding technology such as guns and flamethrowers, and creatures enhanced by technological advancements.
Grail Structure. +5000 /day, +50% creature growth Strikes all enemy stacks with lightning first round of the controller's turn. Occurs in every battle the player participates in, anywhere on the map. Damage is based on the number of buildings in the grail town.
Despite its expensiveness Factory can choose one unit line-up and develop it quite quickly.
Factory has 2 mechanical creatures which can be repaired (i.e. "resurrected") if damaged.
Factory towns can "earn" 5-day income (2500 gold) in advance using Banks every 5 days. Banks are strategically useful at early game, so could be used to faster max upgrade halls and other income-based buildings in order to have great economical advantage at early game and further.
Native terrain is wasteland, which makes it harder for other units to traverse (however, movement penalty is lower than for snow or swamp, which are native terrains of Tower and Fortress, respectively).
Excellent Grail building; Lightning Rod can wipe out the entire army of wandering creatures, or deal significant damage against enemy hero's army. Sending multiple heroes a turn with no army when one of the allied Factory towns has the Lightning Rod can clear almost all enemies, except for units that have Spell immunity or a Spell Damage Reduction.
Cons:
Factory is an expensive town. To have both unit line-ups a lot of resources is needed (70 Crystals just for the lvl 7 creature dwellings and their upgrades).
A lot of the Factory units are quite weak in comparison to other creatures of the same level, especially when unupgraded (especially Armadillos and Couatls).
Most Factory units are quite slow (only Automatons, Sandworms and Couatls have at least 8 Speed), and a lot of the units have very low HP (Halflings, Gunslingers, Couatls are among the most fragile units for their tier).
Factory doesn't have 1-4 level flying units. All other towns besides Inferno and Stronghold have at least one.
