Keeping with the theme of "simple," it won’t take very long to figure out what you’re doing. Nearly everything you need to do requires a mouse click. To direct your units, you select a group (using drag selection), then click on the base you want them to attack. You don’t have to worry about formations, though you will want to think about group composition. While the game seems to encourage attacking a base with the unit type it is weak to, the A.I. (and human opponents) are good at keeping a variety of swarms around, and single unit groups are not a good choice in later battles.
Combat is, for the most part, completely automated. Units will attack any nearby enemy unit, even if they are outmatched. Though this does require a fair amount of babysitting, keeping up with every unit and every base is a challenge – especially since the camera stays close in. On the plus side, units repopulate in Swarmers quickly, so you’re rarely without some units, even if they are basic ones. Usually, the best strategy isn’t complete dominance (though superior numbers help), but rather figuring out which special units give you the greater advantage when capturing enemy Swarmers.
BOID is simple and a bit basic, but in a good way. What it lacks in options it makes up for in strategic depth. If you’re the type of player who needs extras like unit upgrades, resource micro-management, and other RTS features, BOID may not be as satisfying an experience. Players interested in pure strategy, on the other hand, should add BOID to their Steam collection pronto.
