Massive Space Tower Defense
Alien ships fly down towards your planet. Build gun, freezer, rapid and beam turrets, upgrade or sell them and hold out through the waves in four modes.
How to play
Mouse: click the bottom panel or press B to open the build menu, click a turret type and then the place; click a turret to upgrade or sell it (U / S); Space starts the next wave; hold Ctrl to place several. On a phone: tap, plus Next wave / Build / Upgrade / Sell buttons.
Click the game first so it gets the keyboard. P or Esc pauses; the speaker button in the corner mutes the sound.
