This is my 2D project while learning Unity. I’ve always liked tower defense games and I think it was a fun game to practice what I have learnt.

I also wanted to convey the feeling of being overwhelmed by hordes of enemies but emerging victorous in the end.

  • State pattern implemented for ally units AI
    · Movement state: attacking, moving or idle.
    · Attack type state: attacking closest target to unit or attacking closes target to ground point.
  • 3 enemy types are implemented. Two of them have special abilities:
    · Clever Alien (medium size): bullet detection field around it with a medium chance to dash to a nearby position and dodging the bullet.
    · Razer Alien (the big one): attraction field for standard aliens (small ones). They orbit around to defend it.
  • 2 ally types are implemented. One of them has special abilities:
    · Freeze Unit: bullets freeze enemies on impact for a custom amount of time depending on the enemy.
  • Post-processing for bullets effects.
  • Unit selection system
    · Clicking ally units select them.
    · For each unit selected, its enemy target and ground point (if any) are shown.
    · Massive selection of ally units (RTS styled).
  • Shader for line connecting an ally unit and its enemy target.
  • UI: buttons to spawn units (disabling them when reaching the maximum), timer and enemy kills stats.
  • Enemy respawn points and enemy hordes system:
    · Respawns can be easily customized in Unity editor (enemy type, quantity, spawn time, position range).
    · A horde is composed by several respawns which are created one by one.
    · Following horde is started when previous horde is cleared.
