The crowbar is the weapon you start with; used for breaking
glass, destroying boxes, killing easy enemies - everything a gun can
do, without the ammunition.
Pistol
The first gun you get. There's not much to it really - it's just
a pistol.
Machine Gun
One of my most used weapons; the machine gun has a secondary
mode as a Grenade Launcher.
Shotgun
A pretty powerful weapon but very inaccurate at long distances.
Magnum
A very powerful one-shot-kill weapon. But don't use it too much
because ammunition is scarce.
Grenade
Need to kill a big group of enemies fast? Grenade them!
Satchel Charges
Very powerful explosive devices which are detonated by remote.
Crossbow
This weapon is good at killing the Ichthyosaurs as it can be
used underwater and is more powerful than the pistol. It can be used
to sniper enemies too!
Trip Mine
Once placed these emit a laser which, when broken, will explode
the mine.
Rocket Launcher
It is very good at killing lots of enemies at once and shooting
down enemy aircraft and Military tanks.
Gauss Gun
This weapon is very good at very powerful attacks. Like the
Rocket Launcher, it is great at shooting down Military aircraft.
However, it is very unstable and if charged for too long will hurt
you, rather than the enemy.
Gluon Gun
This is a very powerful weapon, which can be used to help
destroy the bosses in Xen (the alien world).
The Hive-hand
This weapon is used by the Alien Grunts. It can be powerful at
medium to long distances but if the enemy gets to close you'll be in
trouble due to it's slow fire rate. It's ammunition returns by
itself.
Snark
You throw these things at people and they will attack them. They
blow up a short period after release. Warning: They will attack you
if there is no-one else to attack.
