Step 1: Single Player Campaign (Casual/Normal)
My first recommendation is to try and complete the game from beginning to end on Casual and/or normal difficulty. You can change the difficulty as often as you want, so revisiting levels later on is no problem. You’ll want to play the game on the lower difficulties first to build up gold and buy upgrades as you progress through the game. Buying these upgrades is essential in order to progress and beat levels later on, on hard. Getting through the campaign should get you at least 12 Achievements worth 245, although you are likely to have unlocked a lot of extra achievements along the way.
Step 2: Miscellaneous Modes and Achievements
After beating the game once, it is advised that you try and get the other mode achievements, in order to get them out of the way and build up gold for your hard playthrough. Make sure to post a score on all survival levels for “Survival Honor” and then beat the AI in Skirmish mode for “Against the Machine”. Make sure to use you gold in order to level up a projectile/troop/spell/room to level 10 for “Upgrayedded”. Also, create a custom castle for “Budding Artitect”. If you missed a miscellaneous achievements through your campaign, you may want to quickly get them out of the way now.
Step 3: Single Player Campaign (Hard)
After completing the game, it's time to start farming some gold, buying upgrades and revisiting levels on hard. You'll want to work your way through the campaign on hard again earning 5 stars on every level. If you are really struggling, just keep playing and revisit the level at a later time.
FARMING GOLD: To farm gold, you'll want to play "Kingdom Quest" > "Ore Mine" > "Frenzy battle!", and use the Tri-Stone to win the level as fast as possible. You should be able to get 5,000 gold every 30 seconds.
Step 4: Xbox Live Ranked Matches
Find a boosting partner HERE.
Now you’ll want to Win an Xbox Live Ranked Match against someone who is ranked higher than you. To boost this, you’ll want to have person 1 to win the first game, then person 2 wins, and then person 1 wins again, and both players will have all 3 achievements.
Legitimately, you’ll just want to go online and use your best strategies to try and win against someone else.
