I ♥ Attack takes place in a post-apocalyptic medical laboratory,
where the player must develop a vaccine to a deadly virus that's about to wipe mankind.
The game is an "immune system simulator", featuring a tower defense gameplay,
where the player controls the different immune cells of the body - White Blood Cells are the 'attacker' type units, Red Blood Cells are the repair units and Garbage Collecting Cells are incharge of clearing out the battle-fields, or a virus might re-emerge.
How to play:
Click and hold one of the circles (top right) to start collecting friendly units (Cleaners/Healers/Defenders).
Click on a body part to release.
Once a cut has been opened inside a body part, viruses will begin attacking that body part, send in defenders to kill them, healers to heal the body part & cut and finally cleaners to gain DNA for improvements.
Mouse scroller - Zoom in/out.
Space - 1st person view of one of your friendly units.
B - End the game.
