Dark Events in Long War 2 are tied to two particular activities COINResearch and COINOps. The COINResearch activity handles tactical Dark Events, while COINOps handles strategy Dark Events. Long War 2 redefines many Dark Events to be of permanent duration, so once achieved they persist for the rest of the campaign. These are typically in the form of an “upgrade” to one or more ADVENT/alien units. Other Dark Events are of limited duration. Because of this, is it possible for more than 3 Dark Events to be active at once (indeed, 10+ not uncommon).

Dark Events in [[Long War 2]] come in two forms: '''Counterinsurgency Ops''' and '''Military R&D'''.  The former represent ADVENT conducting operations to hinder XCOM's progress and bolster their own on the strategic layer. The latter represents improvements made to ADVENT's deployed troops, increasing their performance on the tactical layer; while some are temporary, most of these are ''permanent'' improvements.

Different Dark Events affect specific classes at the following rates.

Depending on difficulty, the first month Dark Events will begin to generate will be different: June for Rookie, May for Veteran and Commander, April for Legend.

Much like vanilla Dark Events, certain designated missions can be conducted to interrupt and prevent the Dark Event from occurring - but unlike vanilla, you will not be given the opportunity to do so if you do not have contact with the region the Dark Event spawns in.  Since the only way to identify them is to increase your resistance network as wide as possible, it is inevitable that some Dark Events will trigger outside of your coverage regardless of how diligent of a commander you are.

ADVENT will attempt to place severe limitations on XCOM operations at the strategic level, in the same way that many Dark Events functioned in vanilla. Fortunately, while they are crippling, they are of limited duration.

These operations will only appear in regions XCOM has contact with. There can be up to two of these being developed in the world, but only one project can happen in each region without an Alien Facility. The cooldown for these operations is 21 days.

ADVENT will improve the quality and quantity of their deployed troops in ways parallel to Force and Strength levels through these events. Some are temporary, but others are ''permanent'' once triggered; over time, [[ADVENT (LW2)|ADVENT's ground forces]] will gain increases in combat effectiveness, as denoted by additional perks and equipment.

Each upgrade applies to a limited set of enemy types, and only a certain random percentage of enemies will actually have the upgrade. This system serves as the Long War 2 equivalent of Long War 1's [[Alien Research (Long War) | Alien Research]], where aliens gain boosts to stats and bonus perks over time. In this case, however, the bonuses are random and tied to interruptible Dark Events, so you have a chance of encountering powerful upgrades early on or of stopping upgrades from occurring.

Latest revision as of 17:20, 7 October 2020

Dark Events in Long War 2 come in two forms: Counterinsurgency Ops and Military R&D. The former represent ADVENT conducting operations to hinder XCOM's progress and bolster their own on the strategic layer. The latter represents improvements made to ADVENT's deployed troops, increasing their performance on the tactical layer; while some are temporary, most of these are permanent improvements.

Depending on difficulty, the first month Dark Events will begin to generate will be different: June for Rookie, May for Veteran and Commander, April for Legend.

Much like vanilla Dark Events, certain designated missions can be conducted to interrupt and prevent the Dark Event from occurring - but unlike vanilla, you will not be given the opportunity to do so if you do not have contact with the region the Dark Event spawns in. Since the only way to identify them is to increase your resistance network as wide as possible, it is inevitable that some Dark Events will trigger outside of your coverage regardless of how diligent of a commander you are.

Counterinsurgency Ops

ADVENT will attempt to place severe limitations on XCOM operations at the strategic level, in the same way that many Dark Events functioned in vanilla. Fortunately, while they are crippling, they are of limited duration.

These operations will only appear in regions XCOM has contact with. There can be up to two of these being developed in the world, but only one project can happen in each region without an Alien Facility. The cooldown for these operations is 21 days.

Military R&D

ADVENT will improve the quality and quantity of their deployed troops in ways parallel to Force and Strength levels through these events. Some are temporary, but others are permanent once triggered; over time, ADVENT's ground forces will gain increases in combat effectiveness, as denoted by additional perks and equipment.

Each upgrade applies to a limited set of enemy types, and only a certain random percentage of enemies will actually have the upgrade. This system serves as the Long War 2 equivalent of Long War 1's Alien Research, where aliens gain boosts to stats and bonus perks over time. In this case, however, the bonuses are random and tied to interruptible Dark Events, so you have a chance of encountering powerful upgrades early on or of stopping upgrades from occurring.

These happen in any region regardless of contact, but only one will be developed at the same time, and only in regions that don't have an Alien Facility. The cooldown for these is 12 days.
