Damage Modifiers
Damage modifiers, synonymous with resistances or vulnerabilities, are a percentage that alter the base damage of any particular damage type. Every unit in the game has a table with different percentages assigned to all of the possible damage types. These values make the units vulnerable to or strong against different damage types.

Please note that these are the actual numbers taken directly from the executable, which the game uses. The numbers from the Official Strategy Guide are incorrect.
(For those interested in changing/hacking the creature damage modifiers, they are located in the Tactical.exe near the end of the file, preceded directly by the decimal variable "26" (offset 781F4 in the CE version). They are listed in left to right order as two byte integers, using the table above as a reference - in groups of 14 variables for each ammo type.)
The Numbers listed below are a reference to the damage chart above (there are 14 sets of damage modifiers, numbered 0-13). The creature entries listed in the Geoscape.exe have a variable which points to which set of damage modifiers the creature uses.
