Battlefield 2 Special Forces

BF2:SF Maps
Devil's Perch, Mass destruction, Surge, Leviathan, Nightflight, Warlord, Iron Gator and Ghost Town.

Grappling Hook:
The Grappling Hook allows a player to reach higher points, such as a rooftop, even if there are no stairs or ladders available. If it sits for a certain amount of time without use - approximately 7 to 12 seconds after being thrown, it will disappear, and it will not be retrievable until the next spawn. It is available to the Assault and Anti-Tank classes.

Night Vision goggles (nvg):
The night vision goggles gives players improved vision in Special Forces' night maps. The night vision goggles can only be used for a limited time only, similar to how long you can sprint. The goggles recharge eventually, so don't worry about using it all up like your ammunition. The night vision goggles limit lateral vision and can lead to the player being dazzled for even longer periods of time by a flash bang. You cannot use the night vision goggles AND the gas mask at the same time. The night vision goggles are available to all classes on maps that are set at night or in the dark.

Zip line
The zip line allows a player to rapidly travel from a high place, such as a rooftop, to a lower one, such as street level. If it sits for a certain amount of time without use (approximately 7 - 12+ seconds after being laid), it will disappear, and you will not be able to get it back until the next spawn. It is available to the sniper and special ops classes.

These things and maps would be interesting to see again in a DLC or future Battlefield game.
