If you were a fan of Tom Clancy's tactical shooters in the past (Rogue Spear, Ghost Recon/Island Thunder, Splinter Cell 1 through Chaos Theory) then this game just shits all over that love and loyalty. I mean we all knew the demise of Tom Clancy was coming when Rainbow Six: Lockdown was released, and the realization probably full set in with Splinter Cell: Conviction, but now it's confirmed with Ghost Recon: Future Soldier. It's not Tom Clancy anymore. There are no tactical or strategic elements in this game, it's full of on-rails sequences where you're completely unable to determine the outcome of events save for where to aim your trigger, and all logic and realism are fully scrubbed in favor of cinematic blunder and Call of Duty thrills.
It's good if you didn't grow up on tactical, realistic, patience-rewarding Tom Clancy titles but it's going to be like tiny papers cuts all over your gums if Rainbow Six Rogue Spear was your favorite game in the series. Stay away from it, Tom Clancy lovers. The TC franchise is dead, but not only that, they're raping it while it's down.
There is zero planning, zero squad command, linear levels, on-rails cinematic shooting, and fast-paced unrealistic shooting. Buy it for the coop and take it back right when you're done, otherwise, stay away. I mean if you thought Ghost Recon 2 strayed too far from the series' roots, then you'll just "love" this entry into the series, lol.
