Small hotfix:

- Sniper-type enemies will attempt to use their mark ability first when firing from squadsight range if possible
- Added 1 turn of global cooldown to EXALT Apprentice Mindfray ability

- Sniper AI update: sniper-type units that have Squadsight ability will now provide fire support to revealed allies even if they aren't revealed themselves yet
- Fixed EXALT Apprentice spawn weight on missions with active Psionic Storm sitrep

- Removed Last Chance passive from the first final mission boss
- Shield HP is increased by 5 for Avatars and the second boss
- Experimental Lost spawn system rework: Lost units now feature 4 fixed tiers of units with increasing stats and damage. This change should have minimal impact on the early-game, but will buff Lost units as the campaign progresses

- Heavy Turret damage is reduced by 1
- Mobility boost from Self-Override ability is reduced
- Minor AI tweaks for sniper-type enemies and the third final mission boss

- ADVENT Turret AI is improved: the turret will now attempt to fire twice using both action points and will enter overwatch if there are no enemies visible
- Sectopod AI is updated: Sectopod no longer has a chance to use Wrath Cannon as it's first or second action and is more likely to fire at flanked enemy if it sees one
- Gatekeeper will no longer automatically close after movement if it started to move while being open
- Sectopod Wrath Cannon is updated to end the turn after being used

- Fixed scamper move change from the previous update (oops)
- EXALT Elite Captain's Mark For Death ability can no longer be used if the unit is mind-controlled

- Fixed Combat Drugs ability description
- Updated scamper moves for the third final mission boss

Updated the third final mission boss:

- Two new abilities are added (Self-Override and Life Link)
- The boss will attempt to escape and recover using these abilities when it's health is too low

- SPARK base aim is increased by 5, base armor is increased by 1 (This buff does not apply to SPARKs that are already in your barracks)

SPARK Cannon changes:

- Weapon upgrade slots are removed (If you already have cannons of any tier in your inventory, this change won't apply until you upgrade them and all installed upgrades will be passed to new weapons as usual)
- Increased clip size by 1 for tier 2 and 2 for tier 3 weapons
- Added +5 aim bonus and +10 crit chance bonus to tier 2 and tier 3 cannons respectively
