That was the case with Cyber Protocol, a game I knew I would be playing just a few seconds into its trailer, awash in flashing neon visuals and a pulsing synth score. Like its trailer, Cyber Protocol greets you with a super stylish, illustrated (but not fully animated) intro sequence with a catchy synthwave soundtrack. It’s slick as hell and sets the tone for a cool hacker adventure presumably full of digital heists and sticking it to the Man, but don’t get used to it. The actual game takes place in a much different looking arena. Imagine a sprawling DayGlo Pac-Man maze where the goal is to find a way out of an automated death trap rather than to collect pellets — though there are plenty of coins and bonus items to pick up if that’s your thing.
Zone A of the cyber protocol
yber Protocol starts out very simply. You control an avatar moving through a vast maze, avoiding deadly hazards to get to the exit. The trick here is that once you start moving in a given direction, you only stop when you hit a wall. Along the way, you can pick up coins to boost your score (solely for bragging rights) or bonus tokens to spend on new skins for your avatar. The hazards start with things like traps that activate a few seconds after you land on them, enemy avatars that move back and forth on a set route, or walls that blast you to bits if you touch them. The mazes are likewise simple, requiring little more than moving forward to reach the end and hardly more thought than that to collect all the items along the way. FIFA 20 Legacy Edition Switch

Within a few short levels, things get much more complicated. New obstacles quickly pile up, like deadly, corridor-filling lasers and locked doors with matching keys, and you’ll find yourself navigating vast fields of spike traps and zipping between armies of hostile avatars before long. The mazes themselves also get progressively trickier, adding portals and disappearing walls, requiring a lot more thought on your part to come out the other side safely. It’s usually a good idea to follow the old adage not to judge a book by its cover, but sometimes that cover is just too good to resist.

Death comes quickly in this game — one touch is enough to end your run — and often you’ll have to launch yourself through the digital maze with no idea what’s waiting for you at the end of the corridor, just hoping it’s not instant death. Even when all the dangers are visible, they can be hard to parse. Everything moves to its own clockwork rhythm, and you’ll need to time enemy movement, bursts of laser fire, and the second of safety you have before traps trigger, while taking into account any portals you’re passing through or any walls that your movement will create or destroy as you pass through special blocks. It’s a lot to keep track of.
