How to approach it
The night opens at wave 4 with 21 enemies arriving in 4 groups. The first group is 5 darts coming in on a looping path. There are no armoured hexagons in this wave. 12 raiders cross the screen without joining the formation. 3 enemies drop capsules: 1 × spread shot and 2 × rapid fire. On Normal you have three lives and one shield charge.
- Raiders weave across the middle of the screen; shoot them from the side they enter rather than chasing them.
- Several capsules fall here; a spread shot makes the rest of the wave much quicker.
