How to Play デンジャラスシード (Japan)
Quick start
- Check α's shot coverage and movement.
- Watch the bullets and use small movements to secure a safe position.
- Use special weapons when enemies overlap.
- Preserve the early ships for the combined fight from stage five.
Controls
Move with the eight-way joystick. Two buttons operate shots and special weapons. Ring Laser, Melt Missile and Hyper Bomb change the attack according to the ship and collected equipment. When a ship loses its life, you move to the next; after combination, you fight using the combined ship's life.
デンジャラスシード (Japan) — About this game
Fight with three ships in succession, then combine the survivors for the later stages. You start with α; when it is destroyed, you move to β and then γ. Each has its own durability and shot rather than simply repeating identical lives. On reaching stage five, the remaining ships combine, so protecting them early also strengthens your later force. Use shots and special weapons against giant insect-like enemies and bosses that escape after some time.
