Haven't checked that one out yet. What is it like?
Spectrum Green has changes to Enemies, Classless Soldiers, and Equipment Tech, each with it's Rock-Paper-Scissors type strength and weakness (S&W).
The first mission Gate Crasher will have a boss 1 of 5 factions that will drop loot that gives you a boost in research for an easy Tech 2 in that area.
Enemies have faction each with their S&W.
Advents are Medium Armor, and no particular S&W.
So the strat is to use Plasma to shred armor, then finish with Mag weapons.
Aegis faction are tech factions, uses laser for accuracy, and shield regeneration. But have little to no armor.
Pandora faction uses poison rounds and nades. And no MECs.
Prometheous uses plasma weapons, fire rounds and nades, no MECs.
Titan are heavy armored MECs, drones. Weakness are smaller pods, and do not use cover.
Law factions are guards and stun lancers, limited to Council missions. They have nasty reinforcements.
Lazarous factions are psi but different. Limited to 1 Thrall at one time that goes into Statis before it gets killed, then activates another Thrall in its place.
Weapon TechMag are good vs unarmored targets.
Laser have accuracy and armor pierce.
Plasma good are shredding armor, with Charging option to shred more armor.
Tier 1 has +1 mod slot, Tier 2 gets +2, Tier 3 gets +3 slots.
Enemies can drop weapons you can use but has no mod slots.
Advent can drop Mag weapons, Aegis drop Lasers, Prometheous drop plasma weapons, Titan drop plate armor, etc.
ItemsItems are made individually, so teching up to 2 or 3 does not auto upgrade old weapons.
Gremlins have 3 types: Combat, Medic, and Utility; and 3 tiers to gain more +Hack, and specific abilities.
Grenade has 1, 2, and 3 tiers, but only T2 allows a choice of Large Radius vs Long Distance.
TroopsThere are 8 types of troops giving them the initial perks.
Scout +12 vision range 1 per turn, +Aim
Sniper +Aim, +20 Aim after hunker.
Spartan +HP, No mobility penalty from weapons
Hunter +Stealth, +Crit
Desperado +Crit, Gunsliner for pistol return fire.
Paladin +Mobility, Blade skill for +dmg.
Codebreaker +Hack, free first turn use of gremlin/drone. Umm, you have to research gremlin/drone.
Soldier I forgot the initial perks for this.
Then basically each rank / level up, you can choose any perk in that rank.
Any trooper can use any weapon and equipment.
As I was levelling up my sniper, he carried an AR/Grenade Launcher, then switch to Sniper/Pistol after some rank and equipment.
Same for my Codebreaker who used a grenade launder until my research for gremlin completed.
