How to Play

Mech Slap - Battleground is a turn-based card battle between Last United Front and Forge Legion.

The goal

Two Apex Units face off on a 9x11 battlefield. Destroy the enemy Apex Unit (40 HP) to win.
The Apex Unit can be attacked at any time, so protect it. Its laser only does 2 damage, but its Anti-matter Shot (range 1, adjacent only) destroys any unit in one shot and hits an enemy Apex Unit for 15. The Anti-matter Shot recharges over 4 turns, and your first shot is ready on your 4th turn.
Surrendering or staying disconnected for 30 seconds loses the match. If both players drop, the match is abandoned with no result.

The host goes first. Each turn lasts 60 seconds; when the timer runs out your turn ends automatically.
At the start of your turn you draw 1 card and gain resources: 4 Metal + 4 Energy base, plus your economy buildings (resources cap at 30).
You start with 7 cards, 15 Metal and 15 Energy. An empty deck causes growing fatigue damage to your Apex Unit.

Click a card in your hand, then a glowing tile. Units deploy in your back 2 rows.
Constructors can build structures from your hand anywhere within their build range (1 tile, 2 for advanced cons). Each constructor builds once per turn.
New units can't act on the turn they arrive, except Haste units (fast scouts like Dash, Scout Buggy, Ferret, Tick), which can move straight away.
Self-destruct: select one of your units or buildings and press Self-destruct to remove it (for example to swap a Metal Drill for a Deep Drill). Self-destructed units leave no wreck. The Apex Unit can't self-destruct.

Select one of your units, then a green tile to move or a red-pulsing enemy to attack. Walkers move 2 (light infantry 3), light tanks 3, heavy tanks, hovers and ships 2, lumbering units 1, aircraft 5 (Dash 4).
Units have movement points (walkers 2, light infantry and light tanks 3, heavy tanks, hovers and ships 2, lumbering units 1, aircraft 5, Dash 4). You can move a unit several times until its points run out, e.g. scout forward and come back. Attacking costs 1 movement point and ends that unit's movement for the turn, so a 3-move unit can move 2 and then attack. Each unit attacks once per turn.
Each unit can attack once per turn. Amber-dashed targets are in reach after moving: clicking them moves and fires in one go.
Targets only return fire if you are inside their range, and return fire deals half normal damage (rounded down, minimum 1). Long-range artillery (Long Tom and Earthshaker range 5, Inferno Array and Sawblade range 8) loses 10% accuracy per tile past 2. Splash weapons also hit enemies next to the target for a third of the damage.
Anti-air hits aircraft hard and has a 50% chance to shoot at any aircraft flying within 1 tile (2 for flak). Submarines can't attack or return fire at aircraft.

Your home rows are always visible. Everywhere else is covered in fog unless one of your units can see it.
Line of sight: most units 2 tiles, aircraft 3, structures 1. Scouts add +1. Radar towers reveal 3 tiles (upkeep 1 Energy per turn), advanced radar 5 tiles (upkeep 2 Energy per turn).
You can only attack what you can see. Radar jammers also hide nearby units until a scout gets within 3 tiles.

Hills block ground units. Rough ground costs 2 movement, but any unit with movement left can always step onto it (using up the rest). All-terrain walkers pay 1. Metal patches give extractors +1 Metal. Tidal Generators must be built on water.
All-terrain walkers (Crawler, Tick, Hound, Hammer, Brute, Mortarman) climb hills and cross rough ground and water with no penalty.
Water: ships +1 ATK. Walkers and tanks pay 2 movement and lose 1 ATK. Hover and amphibious units (Wader, Swamp Strider, Mudskipper, Gator) move freely and get +1 ATK on water.

Destroyed units and buildings leave a wreck worth 80% of their cost. Units can stand on wrecks.
Constructors, Field Medic and Reanimator can reclaim a wreck in reach for Metal and Energy (once per turn).
Reanimator can resurrect a wreck next to it onto your side at full health.

Playable by both factions. Only 1 legendary card per deck.
Rift Gate: once per turn, swap a hand card for a card of your choice from your deck.
Prime Apex: a second, powerful Apex Unit. Losing it doesn't lose the game.
Field Medic: heals all your units within 1 tile (3x3 area) by 3 HP every turn. Reanimator: resurrects wrecks, then needs 2 turns to recharge.
Lag Spike (legendary order): extreme lag, you take another turn straight after this one.
Warhead Silo: can only be built from your turn 5, then builds a missile every 5 turns. Launch it at any tile to destroy everything in a 3x3 area (Apex Units take 15). An enemy anti-nuke with a loaded interceptor (reloads every 2 turns) shoots it down.

One-shot orders, max 5 per deck. Veteran: +50% stats to one unit. Armoured: +1 armour to your units in a 3x3 area. Need for Speed: +1 movement in a 3x3 area.
Spy Drone: see your opponent's hand for 2 turns.
Phase Barrier: your Apex Unit takes no damage from the next 3 attacks (Anti-matter Shot and nukes included) that hit it.
Rage Protocol: every unit on the board, yours AND the enemy's, gets +25% ATK and HP.
Skylift (Last United Front) / Hauler (Forge Legion): air transport. Pick up one of your movable units and drop it on any empty tile.

In the battle room, pick one Apex Unit upgrade: Field Engineer (+1 Metal per turn), Reinforced Hull (+10 Apex Unit HP), Eagle Eye (+1 sight for all your units), Overcharge (Anti-matter Shot recharges in 3 turns) or Power Grid (+1 Energy per turn). If you don't pick, you get a random one.
When the battle starts you can mulligan: click any opening cards to send them back and draw new ones. You can do this once, before you play a card or end your turn.
Select a unit to see an attack preview on every target: damage dealt, hit chance, and the return fire you'll take.

Host a room and pick 2 vs 2. The map is 18x11 and each of the 4 Apex Units starts in their own corner, with teammates side by side on the same edge.
Turns alternate between teams. You see whatever your teammate's units can see, but you can't see their hand.
A player whose Apex Unit is destroyed is out, along with their units. A team loses when both of its Apex Units are destroyed.

Build up to 5 saved decks: 30 cards, max 2 copies each, at least 4 economy buildings.
Host a room or join one from the room list. In the battle room both players pick a side (mirror matches allowed) and a deck, then press Ready.
After a battle, both players can press Rematch to play again on a fresh map. In-progress battles can be watched from the room list.
