Rainbow Six Siege it's a great game, and I have had a lot of fun playing it.

However I would recommend if you are thinking about buying it, to have friends to play with as the game itself, is far more enjoyable when you play with people you know and can easily chat to while playing.

It is a game focused on giving as much information to your team-mates as possible and I find the communication can be lacking when playing with randoms.

Pros:

+ Many different operators with unique abilities to choose from.
+ BattlEye Anti-Cheat
+ R6S is a HIGHLY TACTICAL game.
+ Wonderful graphics.
+ DLC doesn't limit anyone, You can play DLC maps for free and unlock DLC operators with in game renown.
+ Most skins only cost in game currency.

Cons:

- UPLAY, UBISOFT. We got Steam already. Your existence is pointless!!
- Ping is a big ***** issue!!!!
- RANKED matches are not balanced.
- 5 rounds per game is too short.
- No single-player mode.

OVERALL!,
"Excellent game that combines everything a player looking for a HIGH-LEVEL shooting game."
