The game is played on a map of size 17
, the origin being at the top left corner. The map contains a canyon going from the right side of the map to the left. Attackers will spawn on both ends, approaching towards the other side.
Your task is to stop the opponent attackers from reaching your side and to support your own attackers.
Each player starts with 350
money and has 20
lives, losing one for each attacker reaching the own base.
Attackers have a player owning them, a location on the map, movement speed, hitpoints and a bounty for killing them.
They will spawn at both ends of the canyon symmetrically, those attacking player 1 on the left, player 2 on the right. Each turn they move towards the base of their opponent by their movement speed. In case of multiple shortest paths, they will pick one at random.
When their opponent kills them, it will be rewarded by the attacker's bounty.
A tower has an owner, a location, damage, range, reload and cooldown time.
When a tower has an attacker in range and a cooldown time of 0, the tower will shoot at the attacker and be inactive for the next few turns, depending on the reload time.
An attacker is in range of a tower, when the pythagorean distance between them is less than or equal to the tower range.
A player can build and upgrade different types of towers as follows:
Towers can only be built on plateaus, not in the canyon. It is not possible to build a tower at the same cell as another tower.
The gun tower attacks one unit at a time, reducing the hit point by its damage value. In case of multiple possible targets, it will always take the one closest to the own base.
The fire tower damages all opponent attackers in its range. The attack will last 2
turns, damaging the units that are in range during the turn of the attack happening or one turn after.
The glue tower does not cause any damage to the attackers. Instead it will slow them down for some turns. It targets all attackers in range, ignoring those which are already slowed down.
The heal tower does not shoot at opponent attackers. Instead it will heal the attackers of the own team, making it harder for the opponent to kill them.
It is possible to make towers stronger by increasing the damage and range as well as reducing the reload time. Each of these can be upgraded independently up to three times. The upgrade costs for the first, second and third level are 50
The tower strengths are as follows:
