Self Destruct (2008)

Self Destruct is a hectic top-down arcade shooter made for the TIGSource PG competition. Players control a small ship that needs to survive 250 waves of enemies. The hook for this game is that all enemy waves are procedurally generated, making each gameplay sessions different. The small ship is able to shoot, use a shield (limited amount) and launch a nuke that clears the entire screen. Defeated enemies leave behind four types of bonuses: blue (restores the shield), red (upgrades the weapons), yellow (restores the nuke) and green (maxes out everything). Despite using an offline executable, the game originally could only be played when connected to the internet to use the online highscore tables. Later, an offline version was released as well.
