Have you ever asked yourself these questions:

*What is the damage per turn (DPT) of each weapon?*

At short range, is the Rifle auto-shot more deadly than the Heavy Cannon snap-shot?

At long range, is the Laser Rifle more deadly than the Plasma Rifle?

What is the chance of killing a Sectopod with a direct Blaster Bomb hit? What about a Heavy Laser?

A mind-controlled soldier fires a Laser Pistol at a Power-Armored Captain. What is the chance of dealing no damage at all?

Why is the Laser Cannon so useless? Why is the Plasma Beam so overpowered?

How many Fusion Missile Launchers are needed to be more effective against a Battleship than an equivalent number of Plasma Beams?

At the beginning of the game, what is the best weapon layout for 2 interceptors? Cannon + 2Stingray + Avalanche, or Cannon + Stingray + 2Avalanche?

If 3 interceptors with 6 Stingrays engage a Supply Ship, on average, how much damage will the fleet sustain?

How many Fusion Defenses are needed to have a 90% chance of destroying a Battleship? What about 99.9%?

Does the Missile Defenses' low maintenance make them more cost-effective than the Fusion Defenses in comparison to their effective power?

What is the most profitable item to manufacture?I have the mathematically correct answers for all of these questions and many, many more.

I have seen dozens of balance mods, and I believe that 90% of them have been subject to poor choices:

How many balance mods increase the ammo of the Fusion Missile Launcher?

Many.

How many of them have answered the previous question?

"

*How many Fusion Missile Launchers are needed to be more effective against a Battleship than an equivalent number of Plasma Beams?*"

None.

I want to give everyone the correct information, so that hardcore-players can make the best in-game decision to win, and hardcore-mod-makers can make the best game-making decisions for their mods.

For the last few months I've been working on several Google Sheets with formulas and google scripts to calculate lots of metadata about the original game.

These sheets answer all of the above questions,

**calculate, and compare** all the content in the game.

They are separated in 4 files:

Battlescape - Calculations for every soldier, alien, armor, weapon, ammo, grenade, and equipment. DPT (Damage per turn) for every weapon and each fire mode in the game (assumes the player is using X-COM Extender Accuracy). Kill models for each damage type VS each unit.

**Spoiler***More details*:

**DMG** sheet - Regular weapons: DPT calculations. Score of each weapon = DPT + Bonus for TUs left.

For example, if you compare the aimed shot of the Laser Rifle against the Plasma Rifle, the Laser has higher DPT (120 vs 114), but the Plasma has higher Score (102 vs 120). This is because the 2 aimed shots of the Laser leave the soldier with 0% TUs (cannot even turn to face the enemy!), so the Laser gets a Score penalty. However, the Plasma Rifle aimed shot + snap shot leave the soldier with 10% TUs left to move for a line of fire, turn if necessary, or even kneel; so the Plasma gets a Score bonus.

**HE** sheet - DPT and score calculations for all High Explosive weapons and grenades.

Grenades have a different calculation method: RadDmg = Radial damage = power * radius / weight.

Grenades with higher power or radius have higher scores.

Grenades with more weight will be harder to throw, and have lower scores.

**INC** sheet - DPT and score calculations for all Incendiary weapons.

**STUN** sheet - DPT and score calculations for all Stun weapons and smoke grenades.

**Other** sheet - Comparison of clip sizes and weight of all weapons, grenades and equipment.

**HWP** sheet - DPT and score calculations for all tank weapons.

**Armor** sheet - Comparison of all armor values and resistances for X-COM armors, tanks, and aliens.

**Soldiers** sheet - Comparison of all soldier stats.

**Aliens** sheet - DPT and score calculations for all terrorist alien weapons. Comparison of all alien stats.

**KillModel** sheet - Kill models for each damage type VS each unit.

Interception - All X-COM crafts, weapons and UFOs, DPS for all weapons. UFO destroy chances. Full interception simulation models for all weapons VS UFOs, including double and triple interception scenarios. Takes into account craft approach and projectile travel times. Easier to read summary sheets that allow the player to know, for each technology level, what layout of weapons is most effective for 1, 2, and 3 crafts (up to 6 weapon combinations).

Facilities + Prices + Manufacture - Effectiveness calculations for base defenses. 90%, 99%, and 99.9% chances of defending against invading Battleships. Prices, rents, storage sizes and transfer times. Manufacturing costs, and all profitability calculations

Scoring + Research - Comparison of all scores that can be obtained from Battlescape and Geoscape, including alien activity. Research times for all research, compared to scores of each research completion. Total research time for the entire game, depending on the number of labs.

The goals of this project are twofold:

1 - Provide calculated info for vanilla XCOM1 - all the player might ever need decision making in-game. I plan to add much of this information to ufopaedia.org

2 - Provide a template that can be copied, and fully re-written for new mod-makers that want to properly balance their game, without having to make / change any complicated formulas - just filling in the basic numbers, and copy-pasting.

If you have any doubts, if you feel that there is missing information, or if you believe that are any errors, please message me or post in this thread.
