Hello warriors,
大家嚎，

as it turns out, today’s micropatch does not contain only Stronghold fixes (as the patchnotes from RU server declared) but also the elements of the April 1st “fun mode”.
今天更新的迷你补丁并不包含任何的针对要塞模式的修复（毛服的更新补丁中是这么说的），但是其中包含了愚人节的“娱乐模式”的内容

This fun mode involves one special consumable, that will unleash under (yet unknown) circumstances some sort of artillery strike. The patch contained:
这个娱乐模式包含一个特殊的消耗品，会在某种情况下（不知道条件）放出火炮支援。补丁包含了一些：

– new hit sound for this special consumable
这个特殊消耗品的命中声

– new award (was leaked previously)
新的奖章（之前有泄露过）

– the consumable mechanism itself
新的消耗品机制（就是这个特殊的）

The consumable is officially described as “calling a crushing artillery strike to a designated zone, available for tanks from tier 1 to tier 10”.
消耗品的官方说明是这样的“在指定区域呼叫一个毁灭性的火炮支援，1~10级都可用”

Icon:
图标大概是这样的：

Cost: from 50 to 220 gold (depending on tier)
费用：50~220G不等（根据等级决定）

Strike is active for 3 seconds
火炮持续3秒

Loading time is 30 seconds
装填时间是30秒

Blast radius: 10 (meters?)
溅射半径：10（米吗？）

Number of rounds: 3
炮弹数量：3发

Also, there are some firework rounds for artillery, their purpose is not known yet however
火炮还加了一些和烟花有关的声音，但是并不知道是干啥用的

猜测：在指定地区放烟花，三发……
