The Hexapod is best trained in large numbers because of its low survivability but low cost. Building a swarm of Hexapods increases the chances that at least some will survive the enemy's turn, and any surviving Hexapod can deal a sizable amount of damage. Having multiple cities with ample open unit capacity makes it easier to train units in large numbers. Moreover, the Hexapod can ignore movement barriers imposed by terrain and enemy units because it has the creep and sneak skills. This allows it to threaten enemy back lines, as it can move through any space between enemy units. Furthermore, the Hexapod is particularly powerful early-game. Its already high attack can be boosted by the Shaman, which allows it to kill even a Warrior in one hit. Also, its low cost makes it suitable to rush. However, its low health also means that it requires assistance from other units to effectively siege enemy cities or defend against enemy invasions. And, like all units with 10 health or less, the Hexapod is vulnerable to chain attacks by the Knight, which can make Hexapod swarms unfavorable in the mid- and late-game.
The Hexapod is a formidable counter to the Defender. The Hexapod has a strong attack, and its low cost makes it disposable, so it is well suited for killing Defenders. Alternatively, it can ignore any Defenders in or ahead of the enemy's front line because it has the sneak skill.
The Hexapod is similar to the Phychi because they both have low health but high mobility.
