Patch notes are imported from steam. There may be errors. This mostly exists so I can stay on top of them to update the features in our tags and scoring categories (which I do manually), but since many of you liked the idea of staying up to date with all the games in one place I'm working on making this data automated (right now I manually hit it every couple days) with better info and linking in with the game views.

There will be more data and proper atribution here (original author, steam link, original post date, etc) real soon, I promise. This is just like a technical test to see if they're coming in ok at all.

Space Mercenary Defense Force » Update 1.0 – Challenge Invasions, Ship Skins, & TONS MORE

1.0 Release Update

The major 1.0 release is finally here, bringing tons of new content, unlocks, improvements, fixes, and changes! Since this is planned as the final update, I wanted to make it worthwhile and include as much as possible to push Space Mercenary Defense Force to the best it can be. Thank you for playing the game and I hope you enjoy this update.

Challenge Invasions

The primary focus of this update is the new Challenge Invasions, unique challenge runs with gameplay modifiers to overcome. Customise your build to best suit each challenge and try to save the planets from the invading aliens! Complete challenges to unlock additional planetary systems featuring increasingly difficult modifiers and complete all challenges in a system to unlock that system’s bonus challenge! There are 3 planetary systems with 5 challenges each for a total of 15 Challenge Invasions to conquer!

Ship Skins

The next major addition of this update is ship customisation through skins. All 9 ships have a base skin and 3 additional skins to unlock and purchase through playing. From re-colours to new patterns and full sprite changes, these new skins provide bonus late-game objectives to complete and save up your credits for!

Threat Events

Also introduced are 3 new threat events increasing the total to 6. You can no longer encounter the same threat event twice in a row, even between runs. The new threat events are:

  • Pulsing Solar Flare
  • Shooting Star Attack
  • Accelerated Meteor Shower

All threat events have been balanced to occur slightly less frequently over their duration.

Unlock Pop-Up indicator

After unlocking something in-game you will now be prompted, upon returning to the menu, with information on what has been unlocked. E.g: Celestial Modifiers, ship perks, ship skins, bonus Challenge Invasions, Challenge Invasion systems, and Turbo mode.

Ship Turret Fire Rate And Damage Rework

The ship’s turret fire rate has been reworked to be calculated in rounds per second (rps) and all turret fire rate upgrades now show specific stat info on their rps increase or decrease. This means that the ship turret fire rate will no longer scale disproportionately as you acquire more upgrades. Turret damage upgrades now also show how much they affect your damage as a percentage value and all turret upgrades have been tuned to improve overall balance in deciding between branch choices.

Astral Upgrade Changes

Several Astral Upgrades have been altered and rebalanced to improve build customisation and upgrade decisions. Also, some upgrade costs have changed, and some upgrade stacking amounts have changed.

  • Changed on exp pickup upgrades so that they now stack a specified amount of times.
  • Added an on-screen indicator for the exp pickup upgrades when they are active.
  • Added an on-screen indicator for the level up beacon upgrades showing how close it is to being deployed.
  • Changed ‘Turret attack speed on exp pickup’ to increase exp radius on exp pickup.
  • Changed ‘Turret damage on exp pickup’ to decrease ship size on exp pickup.
  • Changed turret attack speed beacon to provide module charge rate instead.
  • Changed how level up beacon upgrades stack – now remaining at being deployed every 3 levels but increasing the beacon’s radius with the upgrade level.
  • Changed the turret shot and hit upgrades so that they can now be upgraded a second time.
  • Changed ‘Heal on boss spawn’ to spawn an HP pickup every 7 minutes.
  • Changed ‘Deal bonus damage to bosses’ to spawn a magnet pickup every 5 minutes.
  • Changed ‘Spawn an HP pickup every 500 kills’ to spawn a coin flip chance event every 800 kills.
  • Changed ‘Spawn a magnet pickup every 250 kills’ to spawn a wheel spin chance event every 1000 kills.
  • Changed ‘Gain an extra life on death’ to heal to 1HP the first time you would receive lethal damage.
  • Lowered ‘Defensive modules charge 25% faster’ to 20%.
Celestial Modifiers

The following Celestial Modifiers have been changed:

  • Scorpio – replaced ‘enemies lose -10%HP’ with ‘encounters grant double score’.
  • Capricorn – changed to ‘a second threat event occurs, threat event duration is -15 seconds’.
Ship Perks

A ship’s perk is no longer required to be unlocked before you can select a perk for that ship. This means that you can equip any unlocked perk on any ship. The locked perk sprite has been changed to a question mark indicating that you can click it.

    • Removed “Retrieve & deliver parts to the marked locations” Escort encounter task.
    • Removed “Defeat the invading wave of enemies” & “Defeat the empowered enemy invaders” Combat encounter tasks.
  • The Praetor’s ship perk requirement now counts all chance event payouts (coin flip, wheel spin, slot machine) instead of just slot machines.

  • Made miniboss HP scale as the game progresses.
