How to play

Servnash (SE.RV.NASH) is a free tower defense game that runs in your browser with no download. You defend Outpost Alpha-7 against waves of enemies that advance on your barricade; the run ends when you die or the barricade falls.

Controls

• Move with WASD or the arrow keys.
• Aim and fire with the mouse.
• Change stance to crouch or go prone. It tightens your spread but costs vision and mobility.
• Grenades and medic packs are limited consumables that refill on resupply.
• Touch controls appear on mobile, so the game is playable without a keyboard.

Your first run

1. Pick a difficulty. Recruit softens every enemy multiplier; see the exact numbers.
2. Choose two weapons and a perk. Cover two different problems rather than picking the two biggest damage numbers; the weapon stats explain the trade.
3. Fight from cover, and expect it to be destroyed, because most of it degrades under fire.
4. Kill field surgeons first. Every second one survives undoes damage you already paid for.
5. Save your 3 grenades and 3 medic packs for the wave that actually threatens the wall, not the first one that looks busy.

Common mistakes

Standing still is the most expensive habit in the game: cover degrades, and units that ignore it will find you eventually. Going prone in an open lane is the second. The spread bonus is real, but a shock runner will reach you before you can stand up and reposition.

Firing at long range with a spread weapon wastes ammunition and costs score, because accuracy is measured across the whole run; see scoring.

Starting loadout

The AR-303 is the safe default: balanced automatic rifle with a 30-round magazine. Pair it with something that answers what it cannot: a close-range option if you keep losing the wall to rushers, or reach if marksmen keep hitting you first.
