BattleGrid structures are divided into three categories: base structures, turrets, and factories.
Base Structures
These are the basic structures that form the backbone of your base.
Outposts expand your cache and control, so they’re necessary to expand your cache so you can build the more expensive factories and artillery.
Extractors harvest resources.
Shields act as a defensive structure, projecting a large shield dome that protects anything within it. Shields are very tough and recharge, but can drop quickly under sustained, concentrated fire.
Turrets
Turrets are your primary defensive structure, though they’re equally effective when used offensively.
Blaster Turrets are cheap, short range, and rapid firing – they act as the best deterrent to units from factories, but are also effective against any other turrets in their range.
Missile Turrets are more expensive, but have a greater range and 100% accuracy, thanks to their tracking missiles. These will usually form your main defense early in the game, since their longer range makes them effective against most units.
Artillery Turrets are the best offensive structure in the game. They’re slow firing and inaccurate, but they deal splash damage and have extremely long range. They’re relatively weak, though, so they need to be protected by other turrets.
Factories
Factories produce your mobile units. These units will move to attack any priority targets, or will spread out and attack whatever is closest to them. Factories come in three flavors:
Tank Factories produce tanks. Tanks are slow but strong, and are able to take a bit of punishment before dying.
Recon Factories produce recon tanks. Recon tanks are the opposite of tanks – they’re quick but weak. They make effective anti-artillery units since they’re able to quickly get within the artillery’s minimum range and fire away at it.
Laser Factories produce laser tanks. Laser tanks are fairly weak, but have a steady laser beam weapon that will always hit and slowly eats away at enemies. This makes them perfect against other units and the weaker turrets.
