Looking for a tower defense game that actually punishes careless play? This Defense Legend 4 APK download for Android brings you the fourth entry in GCenter’s Defense Legend series, a free-to-play sci-fi strategy game with optional in-app purchases. GNVID offers the latest version as an XAPK file.
Defense Legend 4 APK download for Android: story and gameplay
Set in a distant future, the game pits humanity against invading alien forces in a world where giant robots and advanced weaponry decide every battle. Your job is to make sure no enemy gets through.
Placement is everything. You build a defensive line by positioning towers in the right spots, and the developer is clear that without a proper strategy you will not win. It is a demanding tactical game, not a casual tap-fest.
Players who enjoyed Defense Legend 2 or Defense Legend 3: Future War will feel at home, as the fourth part keeps the same look, setting and core gameplay.
Towers, heroes and stages
You get a wide arsenal of towers, including missile launchers, lasers, artillery, ice towers and EMP towers, each suited to different threats.
Controllable heroes with special skills fight alongside your defenses, and an upgrade system boosts the power and range of both towers and heroes. During each stage you manage energy and resources to build and improve your setup.
Stages span deserts, space, forests and military bases, and massive bosses with unique abilities demand different tactics. The 3D graphics feature modern explosion effects, while the simple touch controls respond quickly.
