This is a classic, probably the second best Rainbow Six game ever made after Rainbow Six Rogue Spear. Let me start by telling you that this game will only work if you take 1 extra minute time to download dgVoodoo2 for free, and copying all their DLL files from its dgVoodoo2 zip file folder MS -> X86 and place it in the GOG.galax -> Games -> Rainbow 6 folder, after that, the game works flawlessly, zero crashes, even supports 3440x1440 which, wow, is great. The game per-se is hard for new generation players for several reasons, but I am here to help: 1. Gamers that started towards post-2008 Video Gaming will be confused how the mission starts. Just click the arrows all on top and USE the not so perfect pre-set/pre-loaded Mission Plan. Planning your own mission will just get you frustrated and confused. 2. Remember to NOT play this game in Veteran mode, you should try Easy or Medium, Veteran mode you won't make it past the first Mission unless you got your whole team killed, and you will run out of operatives soon enough. 3. Once in the game, do yourself a favor and just change the keyboard layout to the modern version, but the Unit Command keys, (Alpha Go, Bravo Go, Charly Go, Delta Go) you please in Keypad 1,2,3 and 4. Set crouch to C (you will rarely crouch), Reload to R, and Interact with Environment to F. 4. Patience. You will die a lot at first and probably want to give up. DON'T ! This is how games were in the late 80s-to mid 2005ish. After you do beat the mission, the feeling of achievement will be really amazing. 5. Follow the waypoint lines once in mission. The gaming of 1990s loved waypoint lines, or emphasizing a lot on waypoints (nowadays it is oversimplified), follow that, and as soon as the waypoints don't update, you have to start give commands (Alpha Go, Bravo Go etc). 6. Last point, on rare occasion friendly AIs get stuck when for instance escorting hostages out. Just be patient, go in, and push them for a few seconds, problem solved. Enjoy
