There are five fighters in the squad, this is the first half of the squad. The second half and gunbot will be in October.
The heads/ helmets are interchangeable, there is also a version of the jump pack without wings. If you don't like the default helmets, you can download alternative (and more recognizable) on the purple site for free and replace them.
There are 2 versions of the files at once: unsupported and pre-supported.
