v1.03 Patch Notes! Hall of Fame + Single Player AI

Here's the patch notes for v1.03!

Major Features
- The Hall of Fame can be accessed via the main menu in-game! Each patch, players who score well in leaderboards will be mentioned there. We also have a youtube channel in which some of the playthroughs will be recorded and shown there.
- Single Player AI is available! For players who can't micro a party of heroes even with pausing, your ranged heroes will be able to automate the usage of some of their abilities. For example, the priestess will be able to automatically cast Hallowed Heal on injured allies close by. However, usage of the AI mode will add +5 pause points to your score when uploaded.

NEO Impossible Bosses v1.02 Patch Notes!

Fixed Desync issue with Fujin the Wind Demon
Fixed Desync issue with encounters that spawn units

Arimas the One-Eyed Horror: Extinguish and Void tear abilities restore about 50% less health.
Ji'loch the Imprisoned: Meteoric Corruption now hits less for the initial meteors.
AutoAttack duration increased for bosses: Balazar the Necromancer, Jiloch the Imprisoned and Arimas the One-Eyed Horror. This should make it easier to find timings to attack them.

As usual, the leaderboards will be reset. If there are anymore desyncs do let me know in the forums!

About This Game

NEO Impossible Bosses is a RTS-MOBA Raidboss rush game in which you (and optionally, friends) utilize a number of heroes to defeat the IMPOSSIBLE BOSSES! Inspired by the original custom map "Impossible Bosses" by Psyris and many other MMO raidbosses, each boss is a unique, challenging encounter and has their own signature abilities.


  • A True RTS-MOBA experience - Face off against bosses in a single battle arena, either single player or optionally with friends controlling multiple heroes.
  • Unique and challenging boss encounters - 10 epic bosses await your challenge, taken on at Normal, Hard, and Impossible difficulties. Each difficulty comes with major gameplay differences in boss abilities, not just simply a hitpoint/damage increase.
  • Multiple unit control - Indulge in the idea of literally micro-managing your raiders. Pick from any of the 6 hero classes available and control a team of up to 6 heroes at a time. If things get tough, do a Tactical Pause and issue new orders, or play online with your friends to share the burden.
  • Interesting Abilities and Items - Unlock new and interesting abilities and earn items to improve your chances of taking down the next boss.

  • Competition - Race up the leaderboards. Be the World First guild to take down bosses, or be the most efficient in score.
  • Replays - Review how others on the leaderboard take down bosses, and incorporate their strategies into your own.
  • Ironman mode - For those who want to play the original game mode, a single defeat in any boss encounter means game loss.
