Hello everyone,
大家嚎， 

the supertesters got their hands on the reworked Karelia map – this map will be changed as such:
超测玩家现在拿到了一张重制过的卡累利阿地图—这张图的改动如下：

1) Added a stone to compensate for the other side’s stone, that gave the southern team advantage
1)区加了块石头，用于补偿北边那块石头给他们带来的优势

2) A group of stones here were moved more forward to mirror the formation of stones on the other side of the map, allowing northern side better cover
2)区的话是把石头往前挪了一点，变成和地图另一侧的石头相对称的形状，可以让北边的队伍更好的进行掩护

3) this region was fully reworked, allowing the northern group easier access to the “ledge” area. Now both teams have the same easy access to the camping ledge
3)区则是彻底重制，让北边的队伍可以更加简单的就到达那个“山崖”区域。现在两个队伍想要去山上蹲坑所费的力气是一样多的了。

Hello everyone,
大家嚎， 

supertesters got their hands on the reworked Sand River, that was modified thus:
超测玩家们接触到了新的重制的沙漠小镇地图，改动如下：

1) the mountain was made easily accessible to ensure comfortable gameplay for the upper base team
1)区的山丘现在想要进去会比以前轻松一些，确保了上方出生的队伍的游戏性的舒适

2) reduced the slope of this region to fix this OP erea in assault mode
2)区的斜坡被改低了一些，以修复在夺旗战中这个地方过于OP的问题

3) reduced the height of this area, which makes the lower base harder to defend in standard mode
3)区的高度被降低了，这样标准模式中下方出生的队伍更难进行防守

4) this area was changed by blocking the shots into the right base, which allowed the attackers to crack the base defense too easily
4)区被改成了可以阻挡从右方射来的炮弹，避免进攻方可以过于简单的就突破基地的防守

5) the height of the dune was reduced, a fix of an OP place abused by lower base players
5)区沙丘的高度降低了，修复下方玩家过度利用这个OP点的问题

6) the two areas were reworked to become a regular terrain, so they can be now used to attack. The amount of access points to these areas was increased.
6)区的这几个地方都被重制成了常规地形，所以现在可以用于进行攻击了。而且可以进出这些区域的点也增加了。
