Simply build a settlement during a game of Catan, a settlement costs one lumber, wool, grain and brick resource card and must be at least two spaces away from any other settlement or city and be connected to another settlement or city by a road.

This achievement is only as hard as you make it, it may take a few attempts but follow some basic rules and you will fly through it. Moderate AI will stop trading with you once you take a large lead, so set yourself up for some easy victory points early on and you won't notice the lack of trading.

Development cards will be your greatest ally, so you may choose starting settlements that will give you lots of wool, grain and ore. You can use Soldier cards to steal resources from other players, or Road Building to grab the two VP for the longest road.

Be sure to keep an eye on how many settlements you have as there is a limit to how many you can keep at any one time, upgrade good positions into cities (also gaining VP) so you don't trade all of your resources to build a settlement only to find you can't build any more.

25 Victory Points (VP) is the aim here, this will unlock after winning three matches or gaining 25 points over a few lost matches. Playing against easy AI will unlock this fairly quickly, and if you are desperate then play three player matches to make matches shorter.

Invite another player into an online game of Catan. From the game menu select "Multiplayer", then "Player Match" and finally "Create New Game". Set up a match however you like then invite someone into the lobby, they only need to enter the lobby for it to unlock and you can also get this achievement in someone else's lobby as long as it is a player match.

You must win the 'Longest Road' award 10 times in matches. This will most likely unlock whilst you collect VP for other achievements but it does not take much effort to unlock. The longest road award is given to the player with the longest single road on the map that is over 5 sections long. There are two ways to get this, either gather lots of wood and brick cards or hope you are lucky with development cards and get road building twice. The first method is probably easier and you will probably be doing this anyway to win matches.

When you start a match, position your first settlements in spots that will gain you wood and brick cards then wait until you have enough resources for a road and add it on to one of your settlements. Be sure that you have one long road and not a branching road or it will not count. Win ten matches with the award and you are done.

You can check how long your road is by pulling the right trigger, the number next to the road icon is the number of road sections you have in your longest chain.

You must win the 'Largest Army' award 10 times in matches. Like the longest road award you will need to win an award in the game to unlock this, although for this you must use three soldier development cards during one match to get the award. When you set up a match make sure that the AI you choose do not have a soldier icon next to their name (it is a red/brown man) which indicates they will use soldier cards more often, avoiding these players mean you have a greater chance of winning the award.

Collect wool, grain and ore resource cards and keep buying development cards until you have three soldiers. There are 14 soldier cards out of the 25 development cards available so you will find they are easier to obtain than the other cards. Then all you need to do is play three cards during three of your turns and you win the award, make sure to keep playing soldier cards if any of the AI play one.

You can check how many a player has used by looking at the number of chevrons next to their picture, one chevron is one soldier card played.

You must obtain 100 resource cards through trade, if you play against easy AI characters then you will be able to trade one resource card for two. Keep repeating this whilst playing and you will unlock the achievement after a few games. You can also get this achievement using regular trades, although it will take longer than getting two-for-one against easy AI.

A very difficult achievement indeed, you will need to be either very lucky or very strategic. You must beat three hard AI players in a match, you may end up playing a lot of matches and losing before unlocking this achievement. Here are a few things to remember if you hope to win.

Collect development cards. There are five VP cards in the deck, getting those helps a lot. Road building cards will be important for getting the longest road award and the two VP it holds. Soldier cards are an easy way to gain resources and will hamper the other players' advancement, you can also get two VP for the largest army award.

Positioning settlements. Be sure to pick good spots for your first settlements, allow yourself room to move about the map and settle on other tiles. Make good use of the ports around the edge of the map, using the to reduce port trading costs will help out if you are short on resources.

Trading. Hard AI will rarely trade with you, so never assume you can progress after some friendly trading. However, you will come across the rare opportunity to trade so make sure to seize the moment. Port trading will be a much better option so try to settle on or near ports that favour the resources you gain a lot of.

Don't be afraid to quit a match if things look hopeless, there is no point in wasting time when you are destined to lose, so long as you don't take this mentality into online matches =P

100 VP is equal to winning 10 full matches, or losing a couple of matches with a high score. This will not take very long playing against easy AI and may unlock whilst you attempt other achievements.

250 VP is the target for this achievement, that is 25 full match wins or a lot of losses. Again, playing easy AI makes this a lot easier.

See 'Chancellor of Catan'.

You will need to collect 1000 VP for this achievement, but they must be obtained in online RANKED matches. Follow the basic game hints as stated for the other achievements and you will be able to get this fairly easily, although it will take time. Human players are craftier than computer AI, so you will be playing an entirely different game altogether. Win 100 ranked matches and you will unlock both achievements.
