They're going for $4.99 each on steam. Unfortunately, none of the affiliate websites are offering this low price. The lowest price I found elsewhere was $19.99! Now, that's a deal! Plus, it's a really really good game, I've heard. I just bought it and haven't played yet.
Subhanallah, alhamdulillah, la ilaha illallah, wallahu akbar, wala hawla wala quwata illa billaah.
سبحان الله الحمدلله لا اله الا الله والله اكبر ولا حول ولا قوة الا بالله
