Buy Alien Invasion Tower Defense PC key

Alien Invasion Tower Defense is a 3D strategy game with campaign and endless modes, player-built levels and online PvP. You defend against waves of approaching enemies by placing and upgrading towers, recruiting units, and using special attacks and boosts. Missions have three difficulty levels and two special modes with player handicap.

Defend your position

Each tower has its own advantages and upgrades, with nine types of upgrades and improvements available for every tower:

• Tesla Tower: electricity bounces between enemies.
• Cannon Tower: deals area-of-effect damage.
• Plasma Tower: has a freeze effect.
• Soldier Tower: recruits soldiers.

You can unlock four heroes, each with skills suited to different situations. You can use up to two heroes at each level, and choosing the right ones matters because different heroes are stronger on different levels.

• Willy: moves quickly, deals high damage and can place mines to stop the alien swarm.
• Kristy: uses a rocket launcher for substantial area-of-effect damage and can fire a special freeze missile.
• Thunder: carries a sniper rifle and jetpack, giving him a deadly long-range attack.
• Dave: combines high health and armor with a shotgun and grenade launcher to block enemies.

There are 15 distinct alien enemies, whose traits can force you to change tactics from level to level. Their abilities include teleporting, boosting their speed, sniping, freezing and destroying towers.

Game modes

The campaign and endless modes are joined by real-time online PvP, where both players attack and defend. During a battle, you earn a special currency that you can spend to send additional enemies to your opponent when you spot a gap in their defenses. PvP supports public matchmaking and private games.

Create custom levels

The level builder lets you create maps and publish them for other players to use. You can browse, preview and play community maps, and leave reviews. The builder includes a customizable wave editor and supports three map sizes. You can create maps with up to three paths and 15 enemy waves, designate tower locations, place other props, save your progress and publish your map.
