GenericFactoryGame 1.0.0-preview 攻略

序盤 (credit 20未満)

  • 黒字化は不可能
  • 原料 (ingredient) を割高で購入しないといけないので、どんなに頑張っても赤字が確定している
  • でもめげずに品質 (production quality) の高い商品を輸出し続けて、実績でもって信頼度 (credit) を高めていくしかない

中盤 (credit 20以上　〜　黒字化まで)

  • Perception (遠距離攻撃のみ。黒魔道士系)

    • rifle, spear, (rocket launcher, grenade)
      • 近距離攻撃が弱く、防御も弱いので、敵に近づかれると即アウト
    • animal tracker (食糧問題解決)
    • lucky looter (探索のボーナスup)
      • PER単体だと探索自体は困難
    • salvage operations (レンチ++)

  • Strength (近距離攻撃系、ただし防御低め)

  • shotgun, club, sledgehammer
