We get the requisite actions sequences, too — laser - blaster fights (Caine's
gun, amusingly, sounds like a barking dog),
gravity - defying chases with the help of Caine's
gravity boots (He had wings at one time, but considering that his boots make him fly, that seems a tad showy), ship
battles through Chicago and in space, and plenty of climbing up and jumping across collapsing edifices.
Transmissions is an unofficial expansion to the Half - Life universe, offering a small, single - player experience for players to
battle against the combine once again using a unique
gravity gun to combat enemies and traverse the world.
