Crackerjack Timing (Fallout: New Vegas)

Crackerjack Timing is a three-star (★★★) challenge added in the Fallout: New Vegas add-on Gun Runners' Arsenal.

Obtaining
To complete this challenge the player must kill Mojave Wasteland cazadores with tin grenades, long-fuse dynamite, and time bombs.

Bugs

 * It appears that young cazadores are immune to Time bombs and can be immune to tin grenades. Sometimes they are completely unharmed when the adults are killed in the same proximity.
 * Adult cazadores may be immune to damage from a tin grenade.
 * In the Silver Peak Mine, sneak-killing Cazadors with Long-fuse dynamite does not count towards the achievement.
