We do not support older versions of the game. All you have to do is to launch Steam and let it update your game, it's fully automatic. If on the contrary you insist to stick with an old version then this is your choice.
It's not that we don't want, it's that the Android version can't be modded. Also, people are not at your orders. If you want to ask something do it politely please, don't show yourself rude.
