Summary (AI)
Prime Monster version 1.3 introduces a new Red Box decision at the start of runs, along with two new Tactics—Flight Response and High-Fliers—that convert MP into Bat MPs, and a new Shock Collar item starting with Rotilda. Several existing Tactics have been rebalanced, adjusting costs, damage, uses, and Unity gains to refine gameplay. The update also adds a new debate in Term 2, improves newspaper photo variety, redistributes Story case file probabilities, and reclassifies the Term 3 debate difficulty. Numerous bug fixes address UI issues, audio problems, achievement unlocks, and character behaviors, enhancing stability and overall flow, particularly in Fast Mode and large staff inventories.
Tip: expand all for quick scanning.
  • Updated Story and Event case files so they are drawn after regular cards, instead of replacing cards.
  • Updated "Diss Artist" tactic to apply its Retort at the start of the turn, instead of the end.
  • Updated "Get The Vote Out" tactic so that failed rolls result in +1 Whipped being applied.
  • Updated the categorisation for the Term 3 debate with Slickmouth & Dirtby, from Normal to Controversial.
  • Updated the order of attacks for Rabid Butler in Term 1, so that he attacks before applying Jeering to his MPs.
  • Updated Puke of Wellington in Term 1, so that he applies fewer Defend and Jeering buffs to his MPs.
  • Updated Split the Younger in Term 1, so that he starts with 1 additional loyal MP, and applies Splitting more frequently.
  • Removed a delay from multiple Tactics in Fast Mode.
  • Mummy MPs will now arrange themselves in pyramid formations when possible.
