Single Player:
Weapon Progression system: Pretty cool.Every time you die you get to choose a new weapon loadout.Each mod unlocks an attachment for the weapon. This system also possibly ties in with the multiplayer weapons.
Custom Missions: You can create a mission from two 2 modes,basically this mode is offline co-op.You can also try to hone your commanding skills and unlock weapon mods in this mode.I REALLY was happy to find this mode.You control the Campaign team,and has about 5 maps
Multiplayer:
Love it.There are classic modes,Standard (respawn),And Community Day modes (For Pro members).
Gameplay: much improved from the beta,with more on the way via patch.
Hit detection is incredible,i can shoot a guy once in the head with the weakest weapon and still kill him (unlike CoD) I went 32-14 in a game using the Famas and MP5
Lasting Appeal: Extremely long for SOCOM fans, Till Battlefield 3 for Non-SOCOM fans.
CONS:
No fire mode choice. Single -Auto,Semi
No pistols
No D-pad Lean
No "press to talk" for multiplayer
9.2/10
