Invasion (1978)

Old french abstract game of ground battle for young players.

Goal: Grab 4 of the 10 vital centers of enemy player(s)

Components:
- A grid map with roads, rivers, mountains and lakes
- A cache used for hidden pieces deploiement
- 44 pieces per country (4 minefields, 4 missiles, 16 infantry, 8 paratroopers, 6 tanks and 6 engineers)

Gameplay :
At start, each player secretly deploys his pieces using the provided cache. Then players alternate turns playing 2 pieces each turn. A playing piece can move or eliminates an enemy piece, not both. There is no stacking allowed.
Each piece has its own capacities :
- Minefields don't move but blocks enemy and friendly movement except engineers. They can be eliminated by engineers or missiles however.
- Missiles don't move, are removed when used to destroy any enemy piece in play or to unoccupied bridge on the map.
- Infantry can move up to 3 squares horizontally, vertically or diagonally. They can eliminate other pieces (except mines) by jumping over them horizontally or vertically like in checkers.
- Tanks are treated like infantry but with a 5 squares movement and "jumping" allowance.
- Paratroopers are infantry which can once per game be moved up to 6 squares before being played
- Engineers are infantry which can destroy minefields or when placed on a river square be used as a bridge by other pieces.
