Walkthrough Guide on Kamikaze Pigs
Earning Gold in Kamikaze Pigs
The reason it seems so hard to get money is that each replay earns you less money. You only get more money when your score for a level is above what your best record for a level is. Therefore, the money upgrades should always take priority. Once you have gotten a higher level money upgrade, go back and try for the best combo for each stage. With the +150% money upgrade, and going through all the stages with the highest combo. The hidden levels are the best ones to replay; some of them give you $40,000 on the first try. Doing this strategy I maxed out my upgrades and got 6 stars on all maps.
Tips & Tricks on Kamikaze Pigs
If you can't afford the last upgrade, you can consider selling away the most useless upgrade when you are reaching the last few stages. So in the case of Kamikaze Pigs, the most useless upgrade will be that add money upgrades. I won the game without the last 150% and 100% money upgrades. As long as you have most of the weapon upgrades, the money upgrade isn't needed to clear the hidden boss.
