The demoman serves two roles: First as a defensive player, he can
place tripmines and satchel charges in critical areas to discourage
enemy attacks. He can have up to 3 active satchel charges at one
time which is more than enough to reduce any enemy to a grease spot
on the floor.

The demoman is also a good offensive player. He can use his satchel
charges to blow holes in walls and other destructable objects such as
the grates in TFC levels 'Well' or the tunnels in 'Rock'. His grenade
launcher can be used to create havoc inside enemy bases since the
grenades tend to bounce around a lot. Grenades launched using the
ALT-FIRE button travel further and bounce much more.
