Larmes Vipère

The Larmes Vipère (French: Weeping Viper) is the second Wonder Weapon introduced in The World of the Undead. It first appears in the levels Wreckage and Village. It does not replace the Thundergun.

Effectiveness
The Larmes Vipère is the only weapon that does not cause any damage (the 31-79 JGb215 shrinks them to an insta-kill) and is more of a clearance weapon to help escape traps. It is reccomended to keep this and with Mule Kick it makes a great secondary weapon. If you can get this, the Ray Gun and HK21 you are set for very high rounds.

Serpent de Sang
When Pack-a-Punched it becomes the Serpent de Sang (French: Snake Blood). It's only improvements is that it gains a small bit of damage, it's magazine size is increased to 200 and you get more ammo. This makes it a near useless Pack-a-Punch as reload is quick anyway and the damage bonus isn't great. It's ony really needed if you have run out of ammo or for the Tsunami Easter Egg.

Trivia

 * It is the only Wonder Weapon that does not damage zombies, with the possible exception of the 31-79 JGb215.
