20 Video Game Enemies Designed To RUIN Your Day

19. The Flood - Halo: Combat Evolved

It really cannot be overstated how much Halo did for first-person shooters on consoles, between the tight gameplay, responsive controls and incredible opportunity for addictive LAN gaming, it really is a landmark title that people still look back on with great fondness - hence the recent remastering going down a treat with fans. 

However, not every aspect of the game is so fondly looked back on, and many players will highlight their various encounters with The Flood as being particularly egregious. 

For the uninitiated, The Flood are a swarm a parasitic beings that love nothing more than destroying everything that stands before them. They come in several different forms, but the smaller bug-like variant is definitely the one that will make players sweat the most.

They tend to attack as a swarm, completely overwhelming them with their vast numbers and taking them down can often result in even more being formed due to their tendency to infect those around them. Meaning that battles against these parasitic nasties can take much longer than what you may have signed-up for. 

A scourge in every sense of the word.
