SPIRAL DEFENSE 10.02

Based on a spiral map remastered.

There are three concentric rectangles through which creeps pass, 40 levels. Build a few BASIC TOWERS in the Grassy Dirt area and improve them. Upgrade some POISON and ICE Towers to slow down the enemies. Do not build many towers at the beginning of the game, it is better to upgrade. Take care for targets allowed, some towers attacks land units only, others can target land and air units after level upgrade. Find the best place to build and good combinations for your towers. Manage them so that they attack on the first 2 circles and after the upgrades, some towers with a long range can attack up to the 3rd circle. Build the RESEARCH LABORATORY and perform the first 2-3 levels of updating. Then focus on upgrading to improve your tower skills, as follows: - if you have more slow attack towers, focus on Attack Speed upgrade, - if you have more towers with less damage, focus on the Attack Damage upgrade, - if you have more short range towers, focus on the Attack Range upgrade, - if you have a combination of most towers, continue to upgrade each level 1, 2, 3, 4 ....... All 3 upgrades are great for all types of towers, but you can't finish them all during the game. Type commands in the game: -help, -air, -boss.
