• Swap between your weapons once you buy them.
• Ammo is restored to full before each day for free. Use it or lose it!
• You earn up to 50% extra money based on how accurate you are with your missiles.
• Try to keep up with upgrades - there is no interest for saving money!
• Extra reserve ammo also increases your special weapon ammo! You get x2.0 at Lv.5, x3.0 at Lv.7, and x4.0 at Lv.9.
• You have the opportunity to repair the city every 3 days (Day 3, 6, 9, ...).
• City repairs are expensive, as they cost $100 x Current Day for each 10% HP. Try not to get hit!
