LastCampDefense: How to Beat Waves 16 to 20

To clear Waves 16 to 20 in LastCampDefense, hold your high-impact active abilities for the mid-wave enemy surge, focus ranged fire on fast sprinters, and reinforce your truck's durability so stray hits do not end your run. Waves in this bracket significantly increase enemy density and health, making it impossible to stop every zombie before it reaches your defensive line.

Manage Ability Timing by Wave Phase

Activating all hero skills at the start of a wave leaves your truck vulnerable when the largest group of enemies arrives. Waves 16 through 20 follow a consistent three-phase spawn pattern.

Save explosive skills, piercing shots, and damage buffs until the mid-wave pack converges in the lane. Firing area-of-effect abilities into the thin opening wave wastes damage on low-health targets and triggers long cooldowns right as the densest horde reaches striking distance.

Target Sprinters Before Armored Walkers

Fast-moving infected are the primary threat in Waves 16 through 20. Armored walkers take longer to defeat, but their slow advance gives your squad adequate time to chip away at their health. Sprinters quickly close the gap, slip past basic targeting, and deal rapid damage directly to the truck hull.

Neutralize fast enemies using these tactics:

• Place rapid-fire units in high perches: Station rapid-fire marksmen or machine gunners in top positions with unobstructed sightlines down the entire approach path.
• Apply early crowd control: Hit approaching sprinters with slows or knockbacks to strip away their speed advantage before they mix into heavy frontline packs.
• Aim through the backline: When using manual skill targeting, aim piercing or wide-line abilities straight down the lane. This clears incoming sprinters while still damaging the heavier zombies walking in front of them.

Upgrade Truck Hull Durability

Because enemy health pools scale sharply by Wave 16, relying entirely on offensive firepower will eventually fail when swarms leak through. Upgrading your vehicle hull provides the buffer needed to survive temporary defensive lapses.

If your loadout includes deployable barriers or frontline stall units, cluster them close to the truck's immediate perimeter. Placing barriers too far forward isolates them from your survivors' firing arcs, allowing enemies to break through them without taking concentrated defensive fire.

Balance Sustained Damage and Burst Roles

Relying too heavily on long-cooldown burst units creates damage gaps where normal enemies steadily push forward. Build a roster that balances constant basic attacks with burst tools:

1. Continuous Lane Anchor: Use a rapid-fire ranged survivor to maintain constant chip damage across the path. Stagger squad firing speeds so your units do not enter reload animations at the same moment.
2. Crowd Controller: Deploy a unit with splash damage or knockback to break up clustered packs at mid-range.
3. Burst Specialist: Keep at least one high-impact damage dealer to wipe out emergency clusters that reach point-blank range.

Resource Allocation Priorities

Between waves, concentrate your upgrade currency on your top two primary damage dealers rather than spreading resources evenly across the entire squad. Elevating your main carries ensures their base attack values outpace enemy health scaling. Once your primary shooters can eliminate baseline walkers in two to three hits, allocate remaining funds into truck hull upgrades to absorb unavoidable pressure through Wave 20.
