A corporate tower is a large version of a small corporization. They are unlocked at level 24, and are one of the most sought after items in the game, due to their height. They can be harvested every 24 hours and give 800 coins and 6 XP. To purchase a tower, one must pay a hefty 15,000 coins. They pay for themselves in 19 days. When bought, they give 18 XP. This causes controversy, since they are a high level item, and most city items give more XP on ground contact.
