Sometimes, when you open up a nice big safe area, a tiny visitor may pop up next to one of your bases and disappear before you can say “where did that come from?”. It doesn’t change the gameplay at all, but it does come with a shiny achievement.
New
Added a small hidden cameo animation that can occasionally appear near a base after revealing a sufficiently large empty region. Purely cosmetic – your mines and towers still behave exactly the same.
Added a new Steam achievement: “Hidden Cameo”. Spot the cameo once to unlock it.
Other
Minor polish and internal tweaks around base / hidden effects.
