Comlink - Personal Communication System
This gadget allows you to send and receive messages, as well as to
view objects in remote locations. You can also use it to access useful
tools (which are all explained within the game). When not in use, the
Comlink remains in the bottom right hand corner. This Comlink model is
standard issue equipment given to all Reconstructor Team members. Its
advanced features are especially useful in the 2200's as phones are not
used anymore and are regarded as useless junk from the past.
