✦ AI summary

Operation: Outbreak is a very short zombie corridor shooter with solid gunplay mechanics and atmospheric horror moments, but it suffers from significant technical issues including freezing, black screens, and missing item spawns that harm the experience. Players praise the tense combat and creepy atmosphere, but criticize the minimal length, lack of replayability, and buggy performance, with most viewing it as an unfinished early prologue rather than a complete game worth playing at this stage.

what we have currently is a simple 15 minute corridor shooter. It's decently fun, but there really isn't a reason to play through it multiple times. It can also be a bit buggy, as the first time I played, the starting pistol, ammo, and health pack just didn't spawn, leaving me very confused and trying to sprint past zombies only to be torn apart.

I wanted to like the game. It was extremely dark, even with the flashlight (that hardly was even bright enough), there was little lag, lackluster zombies, the game ended up freezing shortly after the beginning area, i restarted the game 4 times and was getting a black screen every time.

Operation: Outbreak is a really short zombie game, but I think it does a good job of making the most of what it has. I wake up after my squad vehicle gets destroyed during a patrol, and I am left on my own in a city that has been overrun by zombies. The goal is simple, I need to reach the extraction point and stay alive. There is not much story to get through, but I liked having a clear objective from the start instead of spending ages waiting for the game to get going. The shooting is probably the strongest part for me. I start with a pistol and ammunition is limited, so I cannot just run around firing at everything I see. The zombies are fast enough to make getting surrounded a real problem, and there are moments where I would rather keep moving than waste bullets. Healing items and night vision are also limited, which gives the darker areas a bit more tension. I liked that the game makes me think about resources even though the whole thing is over pretty quickly. The city itself looks good for a small free game. The abandoned streets, damaged buildings and underground tunnels give it a decent survival horror atmosphere. I especially liked the darker tunnel sections because the…
