ギルド記念に

ギルド名:EDF日本防衛本部
60レベル以上の方募集中です〜日本ギルドです

上から侵攻してくる敵を倒す防衛ゲームですが、ステータスの成長要素やチップ(装備や特殊効果を与えてくれる要素です)、攻略中のレベルアップなど奥ゆかしい要素が沢山あり、とても楽しいです。

レベルアップで強化出来る物はランダムなので下振れ、上振れがありますが酷くストレスを感じさせる物では無く、戦略性のあるものに留まっています※
上位に散見される5〜15ステージで勝てなくなるというお話ですが、自分は1週間で20ステージ(無課金)まで進められたので、それこそ戦略によって進められる部分があると言えるでしょう。Pay To Winなゲームとは感じませんでした。ただ時間と引き換えという感覚は他よりも強く感じます。

演出もチープではなく、過激でも無くサイバーチックな丁度良い物になっています。

※抽選や追加報酬、兎に角プレイヤーに有利になったり報酬が多く貰える物は動画視聴で貰えるのですが、これは非常に人を選びます…動画視聴をしなくても快適に遊べますが、やはり動画を見れば見るほど…といったデザインです。
