After accessing the internet for the vey first time, the player must now defend their hard drive from a group of invading viruses, the only thing standing between the viruses and total infection is their trusty mouse pointer. Player collects Bits by killing enemies which are spent on upgrades and also count as the score.

Player battles normal viruses in normal waves and faces a boss Viruses every 5 waves

========================
Enemies
========================
Creepy Crawler
Appearance: Purple
Movement: Vertical Movement, Slow
Threat Level: Low

The Creeper Crawler virus is an early and basic variant of the NetCrawler type infection. Whilst it is commonly encountered, due to it's predictable behaviour of crawling direct network paths, it is easy to detect and destroy making it's overall threat level low.

-----------------------------------
Bitter Lemon
Appearance: Yellow
Movement: Randomised movement, Slow
Threat Level: Medium

An early example of a polymorphic virus, Bitter Lemon uses a basic randomiser algorithm to alternate it's movement between multiple network paths making it less predictable and therefore harder to detect and destroy. This makes it slightly more of a threat than most other commonly encountered viruses.

-----------------------------------
Mean Green
Appearance: Green
Movement: Randomised movement, Medium
Threat Level: Medium

A more advanced variant of a polymorphic virus, Mean Green's better randomiser algorithm still allows to alternate it's movement between multiple network paths, however it does in a more intelligent way, allowing it to reach and damage critical system sooner. This makes it slightly more of a threat than most other commonly encountered viruses.

-----------------------------------
Cherry Bomb
Appearance: Red
Movement: Vertical Movement, slow
Threat Level: High

An advanced boot virus containing a secondary payload, Cherry Bomb infects systems in a 2 step process, the initial payload infects the system's boot process and once activated begins to replace files with copies of it's secondary payload, the Code Red virus. Upon detection these payloads are activated, which then attack the core directly.

-----------------------------------
Code Red
Appearance: Red
Movement: Randomised movement, Fast
Threat Level: Medium

The payload virus spawned by the Cherry Bomb infection.

-----------------------------------

Deep Blue
Appearance: Blue
Movement: Vertical Movement, Very Fast
Threat Level: Very High

An advanced variant of the NetCrawler virus, Deep Blue moves through network paths incredibly rapidly. Further increasing it's threat level, it is often found as the payload in Trojan type infections allowing it to breach a system without initial detection, making it even more dangerous if not destroyed quickly once it is detected.

-----------------------------------
Octo Tango
Appearance: Orange
Movement: Snaking, randomised movement, Medium, Turns invisible
Threat Level: High

A variant of a stealth virus, Octo Tango uses memory redirection to disguise itself within a system allowing it to avoid detection for short periods of time. Whilst it is disguised, it is unable to be destroyed, this makes it an incredibly dangerous threat.

========================
Bosses
========================

AdSpawner
Appearance: A collection of pop-up ad windows

Movement: None, each pop-up blocks the mouse from clicking/destroying viruses under it
Threat Level: Medium

-----------------------------------
Trojan
Appearance: A Large Blue Trojan Horse
Movement: Vertical Movement, Slow-Medium,

Pretends to be a bonus, passively generating bits every few seconds.
Releases a group of Deep Blues when destroyed.
Will automatically die and release it's Deep Blue payload at a certain Y value.
Threat Level: High
