Goal. Packets pour in from the gateways (red). Don't let them reach the server. Each leak costs integrity (♥).
Maze. The map is open: Firewalls are cheap walls. Packets always take the shortest open route, so walls make them walk further, past your turrets. You can lengthen the route but never seal it off completely. Hover to preview the new route.
Turrets. Filter (fast), IDS Sniper (long range, armour-piercing), Mortar (splash), Rate Limiter (slows), Router Arc (chain lightning). Spoofed packets fly over your maze, so keep some anti-air. Mortars can't hit flyers.
Credits. Earned from kills and every cleared wave. Upgrade turrets up to level 3. Sell for 70% back (walls refund in full).
Controls. Click to build, drag to paint walls, right-click to cancel. Keys 1–6 pick a tower, Space starts a wave, U upgrades, X sells, T changes targeting, P pauses, F changes speed, wheel zooms. Tap a tower type, then tap the map to preview and tap ✓ to build. Walls paint as you drag. Pinch to zoom, two fingers to pan, long-press to ping your partner.
Co-op. Both players share everything and can build, sell and upgrade at the same time. You see each other's cursors; long-press / Alt-click pings the map.
