We can ( )(play)it together.

We can now play it together
We can only play it together
We can hardly play it together
We can even play it together
We can finally play it together

let's play soccer together. 楼上说的let us play soccer together一般不包含说话的对象。 比如放学了，你跟老师说“让我们（我跟我的同学，不包括老师）走吧”可以用let us go. 如果跟老师说的是let's go.意思就是你要跟老师一起走。
