Other Changes *
Optional Content Toggles - All of the new content (enemies, pilot skills, etc) other than balance changes are possible to turn off if you would like the base-game content experience.
*
Weapon reactor usage reduced - We wanted to encourage players to immediately try out equipment they find, so we reduced the reactor power to equip most gear.
*
Store Changes - Since you can now instantly equip most weapons without needing an additional reactor core, the reputation cost to purchase weapons has increased by 1 and the store options are limited in the first 2 islands.
*
New weapon mechanic: KO effects - Certain weapons will trigger an additional effect if the primary target is killed by the attack.
*
New tile mechanic: Cracking - Certain weapons will cause the ground to crack. If the tile is damaged again, it will shatter, destroying the tile and anything standing on it!
*
New status effect: Boost - This will increase the next attack’s damage by 1. Highly effective for AoE attacks!
*
Unlocking Squads with Coins Change - The cost of unlocking squads with coins has been reduced to account for the extra squads.
Unfair Mode Tips This mode is for veterans looking for even more of a challenge but it might require different strategies than you're used to.
* There will be many more situations where damage is inevitable so it’ll be more important to take losses strategically - depending on the situation, it might be better to lose grid power, sacrifice a pilot, or fail a mission objective.
* Grid power gains are doubled which means it’s much easier to pull back from the brink of defeat. Don’t give up after a few setbacks.
* There is a limit to how many Vek can spawn so sometimes it’s more advantageous to leave some weak Vek alive rather than wiping them out early.
