C-3PO
C-3PO is a protocol droid who seems like an endless fountain of knowledge. Unfortunately that’s almost all he’s good for. He can’t use a weapon, he can’t attack, he can’t run, and he can’t jump.
But what he can do is access the activation panels that have a picture of a protocol droid on them. For this reason alone, C-3PO is invaluable to your success in the game. He can get you into new areas where you can find valuable treasure and items.
R2-D2
This little astromech droid might not look like much, but R2-D2 is critical to the Rebel Alliance. Located on the different worlds around the universe are various kinds of activation panels.
These panels require a certain character to operate them. Only R2-D2 can access the panels with his picture on them and thus perform a task such as opening a door or raising a bridge. R2-D2 is also a very handy droid with lots of surprises.
This astromech can hover in the air for long periods of time. This allows him to fly through the air to get to hard-to-reach areas or items. R2 also can short-circuit any droid and turn it into spare parts.
R4-P17
R4-P17 is an astromech droid like R2-D2 with only the different colors setting them apart. Use R4-P17 to open any locked doors that require the use of an astromech droid, and he can also hover through the air for a short time.
Like R2-D2, he can move past enemy droids unscathed and can deactivate them briefly. This droid might not look like much, but he is key to your success.
TC-14
TC-14 is a protocol droid that is very knowledgeable about things around the galaxy. While slow in movement and lacking any kind of weapon, this character is critical in the game. She can unlock doors where her picture is present on the lock.
