Each one of Weka Invaders' 40 levels consists of a certain number of blocks which hide several Wekas that will eventually emerge and chase Waimanu, and even shoot at him sometimes. Waimanu should drive each Weka out of the blocks and eliminate them before the time runs out. Wekas can be eliminated by either shooting at them or by shaking them off the floor. Points are awarded for each block destroyed and for each eliminated Weka. Also, points are given for destroying the passing UFO, for powerup pickups and for each second left after completing the level. An additional life is awarded when 25,000 points are reached and you can earn one more life every additional 50,000 points after that.
