Radio
Although this level is named after the radio tower near the center of the map, you can expect the fighting to occur pretty much anywhere. This map plays smaller than almost any other map in any gameplay mode, due to the lack of foliage and relative compactness of the island, resulting in small duels all across the map, rather than there being a single location or two where most of the shooting occurs.

There are a couple spots to note, however. The first is the small plant extending upwards from the small lake in the middle of the island; an OICW and plenty of ammo is found here, along with three health boxes, which will be enough to almost completely heal you should you be wounded. Ammo and health are the hallmarks of a classic camping spot, and although the dual entrances to the roof of this facility make for a difficult strategic situation, you can often take people by surprise if you lie prone, and thus are out of sight from ground level.

Secondly, the radio tower itself can attract people who don’t know it as the deathtrap it is. The exterior has both a P90 and an OICW, with corresponding ammo, and the interior has a couple of choke points that make for extremely easy camping. The first of these is the small ledge adjacent to the set of steps that lead up to the first interior room; you can spot people coming up the stairs and wail on them as they attempt to round the next corner. The second location is at the top of the ladder leading to the exterior catwalks that ring the top of the tower. Since people can’t shoot while they’re on a ladder, you’ll have at least a couple of seconds to unload your P90 into the back of anyone attempting to climb up. With the wonkiness of ladders in general, that should be more than enough to kill anyone attempting to reach the sniping spot on top of the tower. Be careful, though: as people catch on to your wily ways, you can expect a vanquished foe to come along and start chucking grenades into your hidey-hole.

Surf
Surf is by far the most open multiplayer map in Far Cry, as it has almost no trees to speak of; almost every spot on the map is fully visible from every other spot, creating a series of long-range engagements on smaller servers, and pure chaos on busier servers. The key here is getting a weapon that’s decent at long range, such as the OICW or AG36, and going to town on players that have just spawned in or haven’t been able to find a weapon with a scope.

As such, deathmatch strategies generally take care of themselves: you’ll have plenty of targets to choose from, so go with whomever is closest to you or whomever seems the weakest. There’s no shortage of decent weapons to choose from, and a mounted minigun position on one of the small islands can help you wrack up the carnage, but you’ll obviously want to be concerned about sniping. The sniper rifle’s spawn location in the tower is where most people will choose to snipe from, obviously enough, so you should check there first when you hear a rifle. If no one appears to be in the tower, than someone may have managed to escape to one of the outlying islands and hide in one of the bushes there.

Camping the rocket launcher is relatively easy, but watch out for grenades.

Camping spots are rare on this map, as there are so few places to hide, but the stairs leading up to the sniper rifle itself are a good spot, especially if you manage to haul a machine gun over to the tower. Another fine spot is behind the crates next to the rocket launcher in the hangar; since you’ll have a rocket launcher and its ammo continually spawning right next to you, you’ll never run out of rounds with which to blast away your hapless foes as they attempt to claim a launcher for themselves. You’ll want to shift your position around inside the hangar every once in a while, though, to avoid being flushed out by a grenade.

There are also a couple of patrol boats on this map, and unlike on Monkeybone, they can actually be used to kill quite a few people when piloted correctly. Since the map is so wide-open, the minigun can easily mow down people walking along the beaches, while your rocket launcher can be periodically fired at the roof of the tower to take out any snipers. Of course, if you do take out a patrol boat and start firing away, you’ll paint a bright red target symbol on yourself, so you may be better off positioning yourself in the deep water behind one of the larger islands and firing away at anyone who comes into view.
