You can delve deeper into the game, of course - there's a wholly new RPG system introduced which lets you learn new skills and craft new items, but that base-assaulting idea is what lies at the core. Attack them from any angle, using any tactics you can muster. Personally we like to take the high-ground and rain arrows down with a compound bow, but there's an argument to be made for direct assaults or more discrete attacks too. Mines, vehicles and melee are all equally valid ways to deal with your foes.
The 'foes' are generally pirates, by the way. Like Far Cry 2 before it, Far Cry 3 doesn't have a continuing story and you don't need to have played the previous games to understand what's going on - which is that you're a tourist who's been kidnapped.
You aren't alone in your plight either; a group of your friends have also been taken and are being held in camps all across the island. When you - a rich American brat with no previous direction in his life - escape, you make it your task to free the others and escape. Luckily, the indigenous tribe take you in and teach you how to be a warrior, among other things.
Freeing the others is a complex task, however. Far Cry 3's world is massive and full of competing factions, so you'll have to run missions for each in order to find out where your friends are - and the allies you take along the way are often far from reliable. The Doctor who offers to shelter your pals and provides you with a boat for eventual escape proves particularly menacing, for example. In fact, he spends most of the game high as a kite and ranting to himself.
Even that's only for starters though, as one of the main negatives some may count against Far Cry is the game’s quantity of adult material. Throughout the course of the game you'll feed all sorts of fetishes, be privy to implied atrocities and do plenty of drugs yourself. This is by no means a game intended for the easily offended.
Not all the drugs and violence are framed badly, however. One of the places where Far Cry 3 iterates positively on its predecessors is bringing the non-human side of the environment into the picture. At the start of the game you're taught to be a hunter and forager as well as a warrior; you'll spend a huge portion of the game stalking wildlife and collecting their skins. These resources then get plied into various upgrade paths, increasing the amount of weapons you can carry and more.
In fact, odd as it sounds, we actually found ourselves spending more time hunting animals than engaging in a lot of the other single player missions. There is all sorts of side content littering Far Cry 3's world, but most of it can be broadly divided into assassination, racing or hunting missions - of which the hunting is the most fun.
