Update 1.6.0 for Invasion: Neo Earth – new combat mechanics

Greetings Neo Earthers!

September’s update 1.6.0 brings forth some big changes in combat mechanics and balancing plus forcefield animations and a whole host of fixes and is live now on Steam. This could well be one of the last updates before leaving early access on October 7th, however even after full release I will still be addressing any bugs that emerge, with planned new content for things like mission packs and new units also on the cards.

Combat mechanics changes – introducing the ‘PWR’ stat

Previously the combat system would use the weapon’s dmg lo stat to try beat the target’s defense, now a dedicated ‘PWR’ stat is used instead. The PWR stat determines whether a weapon will do only it’s minimum damage to a target or do random damage between the low and high range.

PWR => DEF = random damaged done (dmg lo – dmg hi).

if PWR is equal or higher than the target’s DEF then random damage between the lo and hi ranges is
deducted from target’s HP.

PWR < DEF = damage done (dmg lo only).

if PWR is less than the target’s DEf then only the low damage is done.

Cover bonus system for infantry units:

Due to being able to conceal themselves easier than vehicles, Infantry-type units now get a +2 DEF bonus for moving to a square with terrain that provides cover such as forests, hills, fields of cacti, craters etc. Doing so displays a shield icon above the unit sprite and in the UI bar. Naturally enemies can now do the same.


  • Experimental fix for the phase/turn bar and phase cooldown icon appearing too far down the screen on some monitors
  • Fix for shadows not appearing on newly risen soldier zombies
  • Improved the phase cooldown icon


Added forcefield animations for when an enemy is hit by an attack that it is resistant against



  • Alien egg DEF lowered to 3
  • Cyber Wasp and Fire Wasp DEF lowered to 12
  • removed some enemies from Desert and Floodplain maps to prevent overcrowding

Weapon range adjustments:

  • plasma rail cannon range 3>5
  • shredder cannon range 5>3
  • scatter lance range 4>3
  • heavy beamer range 4>3
  • gatling cycler range 3>4
  • all heavy aircraft weapons set to range 4

Three new enemies, environment art and bugfixes for Invasion: Neo Earth 1.4.0


Greetings Neo Earthers! I’m happy to announce that this Summer’s first update is a fruitful one, in 1.4.0 you will find three new enemy types, new environment art and a truckload of bugfixes.

Invasion: Neo Earth is a retro turn-based strategy game currently in early access on Steam, and if you are reading this prior to July 7th, both the game and the OST are currently 25% off in the Steam Summer Sale 2022!

New enemy types:

Grayling Sniper – Not content to pester us with their bullet-shielded infantry and floating gun platforms, the Graylings have deployed sniper weaponry to target us from afar.

Red Heavy – The twisted mutant hybrid monstrosities know as ‘Reds’ have evolved a new form armed with heavy weaponry, grafting metal and flesh together to create a living weapon that is a thorn in the side of our ground units.

Flak Spider – Slow moving but heavily armed anti-aircraft gun platforms that should make any commander think twice about relying too much on air power alone to win the day.

Environment art:

  • New style trees and tile seam fixes applied to mountain levels
  • Comms Base human structure added
  • Supply Base human structure added

Out now on Steam early access – Invasion: Neo Earth!

Good news for fans of retro turn-based strategic action –
Invasion: Neo Earth is releasing in Early Access on Steam today!

All about battling an alien invasion to a soundtrack of Synthwave and Metal, this game takes it’s lead from classics such as Advance Wars and X-com.
Choose your units, customize their weaponry and wage war on insidious aliens, with multiple missions choices at most stages of the campaign.

Why Early Access?
This being the first full-length project of a new development venture, I believe it’s doubly important to hear everyone’s feedback in this final stage of crafting the game into the best it can be, whilst being honest about what is on offer to players.

Finding out what works and what doesn’t is essential to this, so I invite everyone to invest in the early access or even just try the demo and leave your suggestions in steam discussions or via twitter at @iao_dev

Happy alien hunting!
