For those that don't know, Humble Bundle Monthly has XCOM2 at $12. The ringgit may be shit, but $12 only equates to RM55+. Steam isn't going to put this game on sale down that low until at least summer of 2017 (if not longer).

Just cancel your subscription before the end of next month so you don't get charged for the following month.

Oh and before asks if it includes the DLC -  it doesn't.
Also the DLC is garbage, so don't even worry about it.

if Xcom2 is what he wants, i suggest also purchasing Hard West series.

i would recommend Shadowrun but it's pretty short game compared to others.

but Shadowrun is a newbie friendlier game compared to Xcom & Hard West.
