Some say this game isn't for everyone. They're right, unless you're OK to make a supposedly simple rocket spin on itself and immediately crash after an eight-shaped looping, laugh hard, not understand what just happened, try again, get your very first Kerbonaut in space, deorbit him, and leave him stranded without fuel aroun the Mun. Then, you'll become frustrated and start thinking - and reading - hard about planet physics and stuffs like that. It can be frightening, and I hope it's gonna be rewarding. I'm still trying to figure how to nicely orbit something around Kerban. Atmospheric reentry optional.
This game (and its predecessor SWAT3) almost made me get fired from secondary school because of the sleepless nights I spent trying to stop heavily armed and armored robbers with the pepper gun. Its graphics used to be nice, and won't irritate your eyes much today, but that's not the point with SWAT 4 : this game is a classic, it makes people think, improvise and replay its missions again and again, and yes, you can still shoot bad people in the face. Oh thank you GOG for having secured this game for us.
