fun mode is recommended AIM - Destroy all incoming enemy waves by placing towers. You can make their lives difficult by forcing them to take a long path. TOO EASY? THERE ARE 3 MAPS TO TRY - Click the large sideways arrows on the menu screen! Red Gatling Gun - Sustained but limited damage to ground troops. Green Glue Gun - Slows down a single enemy. Blue Missile Launcher - Splash damage and good air attack. Purple Tesla Turret - Large damage to close targets (ground or air) Here's some of the fun features: 1) Fieldrunner style pathfinding - Enemies spawn at an entrance and will take the shortest path to an exit. 2) Towers can be placed on the map by clicking, and they dynamically alter the route the enemies can take. 3) Guns target the enemy closest to where they are currently pointing then lock on until they are out of range.
