unlockables meaning in English

可以解锁的

The experience is over fairly quickly . there are a number of really good unlockables to go back and earn , though you can already get them online right now
打分的人竟然抱怨游戏不够长？他们自己都说有10个小时左右的长度，还“很短” ？因为有不少很好的隐藏因素但是可以在网上拿到而给低分？有比这个更加搞笑的打分么？
The good : the puzzles are varied and challenging ; the game sticks closely to the book and film but adds new content of its own to pad out the adventure ; relatively lengthy storyline with secrets and unlockables to find
优点：迷题种类多样且具挑战性；游戏和原著、电影非常接近，但是增添了自己的一些东西来加长冒险的流程；相对较长的故事情节中有各种秘密和可额外开启的内容供玩家探索。
