大南斯拉夫（Huge-oslavia）

作为南斯拉夫，占领你所有的邻国（奥地利、匈牙利、罗马尼亚、保加利亚、阿尔巴尼亚、意大利和希腊）。

This 成就 requires  南斯拉夫 to control all neighboring nations' cores except Istanbul.

Strategy - method 1

Rush communist - you need 40% support to 废除君主制. Do Form Peasant Councils早于Mutual Economic Aid and pick up a communist advisor to finish as soon as possible. Once communist, declare on  奥地利 and finish the war before the Anschluss. Annex to take advantage of their civs. Declare on  希腊 after the justification on Austria. You want to take out Greece early so they don't join the Allies when world tension jumps.  罗马尼亚 guarantees them and you, so they don't join. Annex for their resources and their navy. World tension is now too high to grab the other countries without triggering a  法国 or  UK guarantee, so build up your army and industry. Build some forts from east of Fiume through Zagreb as a defensive line. Build units to hold that line,  匈牙利, and to attack  阿尔巴尼亚. Also place units next to Zara. Join Comintern. Set up some collaborations. Wait until the  Soviet's are working to Demand Bessarabia (mid-1940). If the Soviets get Bessarabia, you won't be able to get it. Do a quick justification against  意大利 to and call in the Soviets to kick off the war. By this time Romania should be in the Axis, and once they are called in, they will reject the demand. Rush in to clear out Albania so you can reinforce the Romania/Bulgaria defenses.  保加利亚 may not be called in right off. Take advantage of the Zara exploit. Attack the Italians there, but don't take the port. They keep coming back and when they land they have low org, so you can keep taking them out. An easy way to do this is to hold ctrl + alt + right click. This allows troops to attack a province without moving into the province after the enemy has been defeated. Turn off allied supply at your Split naval base to keep the Soviets from "helping" you and taking the port. They don't try to land anywhere else. Set your subs on convoy raiding in Central Med to help the UK in Africa. Let them wear themselves out attacking you for a while. Keep wiping out the Italians that land in Zara. Slowly expand out if you have favorable matchups. A few months into 1941, Italy should be stretched thin. You want to make sure you take them before the Allies, so you get the puppet collaboration government. Start to push in northern Italy, and and should be able to get naval supremacy in Central Med and invade Sicily from Greece. Push up and potentially set a secondary invasion from Palermo to Rome. Push and Italy should fall and give you the puppet. Now focus on taking out Hungary, Romania, and Bulgaria. Make advantageous pushes. They have some death stacks, but if you concentrate forces you should be able to find some points to surround some of these. When Hungary, Romania, and Bulgaria are gone,  德国 forces will be thin from pushing on the Soviets. Start to push up and finish off the war. Take the required provinces in the peace conference. Remember to grab Dodecaneso (Greek core, Italian starting province) it is next to  土耳其 and easy to overlook. Use the autonomy system to build in Italy and annex them.

One difficulty with this strategy is a major risk that Greece will get guaranteed by either France or the UK (or both), because you generate too much world tension by the two justifications and by annexation of Austria. One possible trick is to drag the war with Austria long enough that you declare on Greece 早于 accepting Austria's capitulation. But that carries a risk of losing Austria entirely to the Anschluss. Even if you pull all stops, the absolute earliest you'll be able to declare on Greece is January 1938, so, it's a tight schedule. (It is also possible for France to decide to guarantee Greece while you're still fighting Austria, so, delaying Austrian capitulation is not a sure way to prevent Allied guarantee.)

Strategy - method 2

Start as in method 1. Skip the Communist advisor (in this strategy, timing is not so critical) and use your first political power to switch to War Economy as soon as you go Communist. Annex Austria. Do 泛斯拉夫工人大会. Stage a peasant uprising in Bulgaria and invite it into your faction. Wait for Albania to be annexed, which lets you bypass the Invite Albania focus. Do 泛巴尔干倡议. Kick Bulgaria out of the faction, join Comintern, and start justifying on Bulgaria. In the mean time, work on a peasant uprising in Romania.

When the peasant uprising occurs in Romania, immediately start justifying on Communist Romania (it takes 125 days). The civil war should be over by the time your justification arrives. If it drags too long, you can send volunteers to Communist Romania to help them (the game sees nothing wrong with you sending volunteers to a country and justifying on the same country at the same time.) Be sure to finish conquering Romania before the Soviet Union demands Bessarabia.

You can try to do an uprising in Hungary, but you'll likely run out of time (Hungary will join the Axis before your uprising wins). You might be tempted to prepare it and launch it when Germany declares on the Soviet Union. Don't do that (Hungarian People's Republic will join Comintern, and you won't be able to annex it.)

In 1940, Italy will declare on Greece. With no Bulgaria, no direct land route from Rome to Greece, British naval dominance in the Med, and only a narrow mountainous border between Albania and Greece, Italy will quickly get stuck. Build up an army, build some forts along the border with Germany and Hungary.

In 1941, Germany will declare on the Soviet Union. By then, Italy will be exhausted and low on equipment, a big chunk of its army will be stuck in Albania with low supply. You'll have two full armies, your northern flank will be very difficult to breach (mountains and forts), and the Soviet Union will help you defend the long border with Hungary. A hard push and some encirclements should topple Mussolini and give you Regno Del Sud as a puppet.

With the Axis down from five to two members (Germany and Hungary) and with Germany denied Austrian industry, Germany should be relatively easy to take down, and your participation score may be as much as 25%, more than enough to demand all of Italy and Hungary.

After the peace conference, you reduce Italian autonomy to zero to annex it. With any luck, Greece leaves the Allies and you can pull the same peasant uprising trick, easily capitulating them. If not, it should not be too difficult to occupy them with the help of the Soviet Union (you may want to prepare paratrooper/marine invasions of the islands in advance).
