在《怪物火车》的惊心动魄之旅中，契约25难度让无数玩家体验了前所未有的挑战。面对这艰难的关卡，不少玩家开始寻求升级代码的奥秘，以期突破困境。今天，就让我们揭开这神秘面纱，一探究竟！
《怪物火车》升级代码揭秘：一览无遗！
游戏存档目录
C:\Users\用户名\AppData\LocalLow\Shiny Shoe\MonsterTrain\saves
打开save-singlePlayer.json
使用Notepad++打开，记事本虽然也能用，但编辑起来较为困难，笔记本的搜索功能有限，难以搜索到所有代码，但只要理解了，修改起来也不算难。
升级代码
{"cardDataID":"82e21764-56cb-4e41-882f-ab3dd0c1dcbc","cardModifiers":{"additionalDamage":0,"additionalMaxHP":0,"additionalCost":0,"additionalXCost":0,"additionalHeal":0,"additionalSize":0,"cardTraitReplacements":[],"cardUpgrades":[]}}
上面这条完整卡牌代码中，最后的cardUpgrades括号内就是添加升级代码的位置。
升级代码样式如下（双重攻击）：
{"cardUpgradeDataId":"fe8b9475-4e26-43b6-9073-d77bba555ca4","attackDamage":0,"additionalHP":0,"costReduction":0,"xCostReduction":0,"additionalHeal":0,"additionalSize":0,"statusEffectUpgrades":[{"statusId":"multistrike","count":1}],"useUpgradeHighlightTextTags":true}
我们复制这条代码放到cardUpgrades的括号中卡牌就有了双重攻击，完整的代码如下{"cardDataID":"82e21764-56cb-4e41-882f-ab3dd0c1dcbc","cardModifiers":{"additionalDamage":0,"additionalMaxHP":0,"additionalCost":0,"additionalXCost":0,"additionalHeal":0,"additionalSize":0,"cardTraitReplacements":[],"cardUpgrades":[{"cardUpgradeDataId":"fe8b9475-4e26-43b6-9073-d77bba555ca4","attackDamage":0,"additionalHP":0,"costReduction":0,"xCostReduction":0,"additionalHeal":0,"additionalSize":0,"statusEffectUpgrades":[{"statusId":"multistrike","count":1}],"useUpgradeHighlightTextTags":true} ]}}
