X-COM: Apocalypse Strategy Guide/Equipment

Megapol LawPistol
Quite decent in the first week, after that it's obsolete and should be avoided. As a single-handed weapon, it allows the use of a second item (grenade, medikit, a second gun) in the other hand without lowering accuracy.

Megapol Plasma Gun
Much better than it's predecessor. This gun never really becomes obsolete but it's not really not that effective. As a single-handed weapon, it allows the use of a second item (grenade, medikit, a second gun) in the other hand without lowering accuracy.

Marsec M4000 Machine Gun
The same thing can be said about this weapon as about the basic pistol, except on the higher difficulties where it's obsolete before the game starts.

Megapol Laser Sniper Gun
An excellent long range weapon. While it's damage capabilities leaves a lot of room for improvement just remember that if you miss damage will be exactly 0, so hitting is better than missing. While using this gun agents will progress relatively rapidly in their accuracy skills, making it a good weapon for training.
