- Expand the Arsenal: Gather currency through kills and wave clears to unlock stronger guns, deployable structures, traps, and tools that reshape your strategic action flow.
- Reclaim Territory: Push outward by clearing sections filled with tougher undead variants, gaining space for new fortifications that influence future runs and difficulty spikes.

How Upgrades Affect Your Action
Upgrades shift the pace, weight, and outcome of every battle by expanding offense, strengthening defenses, and improving survivability at the same time. Stronger firearms reduce panic moments during dense swarms while reinforced structures buy valuable seconds during late-wave assaults. Added utility tools enrich your tactical options, creating smoother transitions between shooting, defending, and advancing through hostile ground.
