They're dead-end nodes so you are free to ignore them, but the plot will still assume you've done them anyway. Gameplay and Story Segregation: Disarray leaves a request for you to retrieve some files from a couple of level 3 nodes.
The best example is the Bug series of programs, with 5 movement, 1 max size, but deliver strong melee damage. Fragile Speedster: A few programs behave like this, with high speed but low maximum capacity.Featureless Protagonist: You don't even get to see your chat avatar.Some levels even feature enemy-controlled copies of programs available to you. Evil Counterpart: Common hostile programs mimic the behavior of some of yours - for instance, the Warden series is your Golem programs in a different skin.Take care that it doesn't erase the program in the process. Cast from Hit Points: A few of your program abilities consume their own sectors as a cost.Most of your other programs obsoleted by better versions, but the Bit-Man is the first-level program that remains relevant across the whole game. Boring, but Practical: The Bit-Man is the only one that can create and erase terrain for programs to travel over.Certain actions have a space requirement, demanding that the program have at least that many sectors on the field before that action can be used. Your programs have multiple types of actions that can be used to attack, heal, buff, debuff, or alter the battlefield. This is a double-edged sword larger programs take more firepower to take down but can are a bigger target and obstruct other programs, while smaller programs can slip past enemy attack ranges but are much more fragile. The health of your programs is tied to their movement: As programs traverse the board, they take up more space up to their maximum capacity, leaving behind "trails" that only they can move through but are vulnerable to attacks.
You have limited upload points and your units to deploy are your programs. The main game, once you access a node, is a turn-based strategy.
However, intermittent interruptions plague the network, courtesy of a "Nightfall" hacker, and you have to work your way through the net to find leads on the hacker and how to stop the outages.
You play as a newly-recruited SMART agent, and are tasked with hacking into various systems to disable security to help retrieve locked files or remove corrupted security programs. The game has very little to do with the toy line itself you have a choice of Spybot at the start of the game, but this choice is completely cosmetic.
Spybot: The Nightfall Incident is an online game released in 2002, made to complement LEGO's "Spybotics" product.
