Items
Items are defensive things that you can deploy onto land tiles that you own. If another player attempts to capture the land, they will suffer the effect of the item.
Once deployed, you cannot remove your own items from the tiles they are on.
Every player sees Digits on tiles they own, indicating the total number of items on adjacent tiles they do not own.
Mines
Mines will explode when stepped on, resulting in the offending player receiving a Death Timeout. This adds to the "Death" count of the offending player and to your "Kill" count.
All players in the match will be notified of this event. The explosion effect and location will be seen by all players. The tile where the explosion occurs will become visible (no fog) for all players for a duration of 2.0 sec.
A skull decal will be left behind to commemorate the occasion.
During the timeout a player cannot perform any game actions. All of their cities pause production for the duration.
The timeout duration is 10 seconds.
The tile will be converted to Destroyed Land, thereby providing no more resources for the remainder of the game.
Decoys
Decoys are harmless and will break when stepped on. The other player will successfully capture the tile.
The purpose of decoys is to confuse the other player and make the Minesweeper digits puzzle more difficult for them to solve.
The presence of a decoy will add an asterisk (*) to the digits other players see on adjacent tiles. This provides a hint to them, without directly revealing the actual location of the decoy.
Smoke Traps
All tiles adjacent to the trap's tile, that are owned by the offending player, will have their digits obscured with Smoke.
Similar to a Decoy, a Smoke Trap will add an asterisk (*) to adjacent digits. This will trick players to fall into the trap.
