How to approach it
The night opens at wave 4 with 21 enemies arriving in 4 groups. The first group is 4 raiders coming in on a weaving crossing. There are no armoured hexagons in this wave. 10 raiders cross the screen without joining the formation. 2 enemies drop capsules: 1 × spread shot and 1 × shield. On Hard you have three lives, no shield and quick, frequent enemy fire.
- Raiders weave across the middle of the screen; shoot them from the side they enter rather than chasing them.
- Stay low and to one side while the groups fly in, then work across the formation from that side.
