Alien Level (LWR)

Alien Levels and Alien Research

Aliens increase in Level as the game progresses and by gaining Research.

Aliens gain Research via a variety of other methods, so under-performing at the strategic or tactical level can accelerate their progression. Alien Level is modified by Difficulty Level.

The formula for the alien Level is:

Level = 1 + (Research + Days Passed) / 50 * Difficulty Modifier

Aliens start at Level 1 and can progress to Level 15

Increasing and Decreasing Alien Research

Research starts at 0. It is always clamped between [0.1 * Days Passed] and [0.5 * Days Passed]. Thus, it will always grow by at least 10% of the days passed and can never exceed 50% of the days passed.

Increasing Alien Research

• +2 per month per country under alien control
• +5 for a successful abduction mission (modified by Campaign Length)
• +20 for successful raid on XCOM HQ
• +2 for a successful research mission by a landed Scout (modified by Campaign Length) (increases by 10% per month)
• +3 for a successful research mission by a landed Raider (modified by Campaign Length) (increases by 10% per month)
• +4 for a successful research mission by a landed Abductor (modified by Campaign Length) (increases by 10% per month)
• +5 for a successful research mission by a landed Terror Ship (modified by Campaign Length) (increases by 10% per month)
• +1 per lost XCOM soldier on a failed mission (killed or left behind) (modified by Campaign Length)
• +50 per incorrect accusation of a country of harboring the EXALT base

Decreasing Alien Research

• -10 per successful assault on an Alien Base
• -2-12 per Combat Patrol sent out by XCOM

Effects of Alien Level

Troop Strength

Alien Level's most notable and significant effect is to increase the strength of alien ground forces. Specifically:

• Higher levels allows stronger aliens types to be fielded
• Higher levels increases that stats of alien ground forces
• Higher levels make alien leaders stronger

See Alien Life Forms for more information on the effect of Alien Level on alien ground forces.

Decreased Alien Resource Consumption

• If Alien Level is 1-7, alien missions cost 100% of their base required resources.
• If Alien Level is 8-14, alien missions cost 72% of required resources.
• If Alien Level is 15+, alien missions cost 40% of required resources.

Pod Size

The number of aliens allowed in each pod is directly dependent upon current research points:

• Small (Alien Level 1+): 2-4 aliens per pod
• Medium (Alien Level 3+): 3-6 aliens per pod
• Large (Alien Level 6+): 4-8 aliens per pod

Meld Rewards

Alien Level helps determine the rewards obtained from meld canisters.

Meld Canister Amount = 0.3 * Alien Resources (Min: 33%) * (1 + Alien Level/6) * Difficulty Modifier[1, 1.3, 1.6, 2.0]

The amount of meld per canister is set to a minimum of 10 and is affected by Dynamic War.

UFO Upgrades

All UFOs gain a additional HP every Alien Level. Some UFOs will also gain upgraded weapons over time:
