Undead Invasion: Days, Waves, And Upgrades

Controls stay familiar — move and shoot — so attention can stay on wave reading and resource tradeoffs. Between days you strengthen weapons and defenses. Every purchase is a bet on the next assault, because a wipe sends you back to day one.

The tension is not only the horde on screen. It is whether your last upgrade actually covers the next spike in pressure.

Survival habits that matter

Think in days, not single kills:

  • Fix the weakest wall first: Fancy guns do not help if the line collapses behind you.
  • Bank a flexible upgrade: Some waves punish pure damage; keep one defensive option ready.
  • Clear densest packs early: Letting crowds merge is how runs spiral.
  • Accept short runs as scouting: Learning wave tells is part of the roguelike loop.
