Minigames[]
Republic Defender[]
With the exception of the Probe Droid the B1 Battle Droid is weakest droid in the game and is usually the first enemy you will encounter on any stage. Although these basic droids do not pose much of a threat to your defenses, they tend to come in small and large masses. A great way to deal with Battle Droids is to use turrets that have the ability to damage several droids at once, making the Mortar Cannon and Thermal Grenade Turret arguably the best turrets to use against them. Still, a simple group of blaster turrets provides a sufficient defense against Battle Droids in early stages.
Blaster Training[]
Battle Droids are one of the two enemies that appear in Blaster Training, the other being the B2 Super Battle Droid. Although weaker than Super Battle Droids, they are much harder to score criticals on. Bonus stages consist of shooting Battle Droid parts to score additional points.
Combat Zones[]
Rhyloth[]
B1 Battle Droids are the most common enemy on Ryloth and generate constantly. There are also a few stationed Battle Droids that don't march with the main advance.
Battle of Umbara[]
B1 Battle Droids are among the most common enemies met in the Umbara combat zone. They are also the second weakest enemies players will encounter as it often only takes one shot from most blasters or one lightsaber slash to defeat them.

B1 Battle Droids also appear on Carlac, though only in the Separatist crashed cruiser area. They are the weakest enemy in that area and appear like on Umbara

A grenadier variant also exists, but is much rarer. These droids wield a grenade launcher that deals high damage and can knock players to the ground. In the Airfield mission one can be found in the room across from the area with the Umbaran Hover Tanks. Others are found wandering in the forests, particularly where the Rancor is located.
