弾幕の器2は7種のアイテムを駆使して敵を攻略する「弾幕シューティングゲーム」です。敵は100種類!。さらに4つのモードが楽しめる! -------------------------------------------- ●共通ルール 自機はシールド制で4ダメージまで耐える。ただし敵弾の種類によってダメージが変わるので注意(大きい弾ほど大ダメージ)。 -------------------------------------------- ●EASYモード 序盤はチュートリアル。メニューのテキストを確認してから挑戦しよう。 自動照準搭載で比較的に弾避けに専念できます。 -------------------------------------------- ●HARDモード ここからが本番。パズルの要素を追加した弾幕ゲーム。アイテムを利用して敵艦を弱体化させるのがポイント。 ○上級者の方へ HARDモードはクリア時の状況に応じてメニューに表示されるダイヤの数が変わります。ダイヤの獲得条件は以下の様になり、全ての条件を同時に満たすと3つ獲得できます。 ・敵を攻略 ・攻略時にノーダメージ ・攻略時にタイマーが0以上 前作の艦艇を全て攻略できた方にはノーダメージでのクリアも可能でしょうが、タイマーが0になる前に攻略するためにはアイテムを駆使する必要があります。 -------------------------------------------- ●HELLモード 兵装が利用できない代わりに支援機が追加されるモード。難易度は上がると思いきや、意外とクリアできてしまう。 -------------------------------------------- ●Lunaticモード HELLモードが意外と簡単なため急遽追加したモード。兵装も支援機もなし。さらにシールドが無いため1発でも被弾したら終わり。 -------------------------------------------- youtubeに攻略動画をアップしました。行き詰まっている方はyoutubeにて「弾幕の器2 攻略」で検索してみてください。
