AIM - Destroy all incoming enemy waves by placing towers. You can make their lives difficult by forcing them to take a long path. The fun difficulty is straightforward! Try moving to Easy or above for a challenge. *** THERE ARE 2 New MAPS TO TRY *** by clicking the large sideways arrows on the menu screen! Budder Gun - Sustained but with minor damage to ground troops. Emerald Glue Gun - Slows down a single enemy. Diamond Missile Launcher - Splash damage and good air attack. Amethyst Tesla Turret - Large damage to close targets (ground or air) Here are 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.
