Is this game Dead? No! It's Undead! Hehehe. To avoid GAME CRASH set "Model / Texture detail" in "Options" - "Video" to "High" ("Medium" for 100% fix). Don't set "Shader detail" lower than "High" or you will not see Gore System. Don't play in "Full screen" mode because ALT-TABing and different software overlays and notifications will produce lags, visual glitches, game crash. Some Workshop items can make game start slow or not start, lag, crash. Steam - Library - Contagion - [RightMouseButton] - Properties - General - Launch Options - [LeftMouseButton] - [Type "-novid -nomenuvid"] - [Close window]. Option "-novid" disables max sound volume startup video(s). Option "-nomenuvid" disables game menu background video(s).

I'd describe it as something between Left 4 Dead & Payday mixed with some F.E.A.R and Cry Of Fear. Lets start with the pros: -The lineup of weapons and tools is diverse and full of solid sidegrades and usefull items with minimal bloat or reskins. My favorite item is the crossbow with retrievable ammo but slow reload. -Similarly to Payday & some extent Left 4 Dead, every round is unique with variations like randomized starting loadout, reandom spawn location, random loot and enemies though key items, level layout & objectives do not change that much. -No plot armor. Once you're infected, you're infected and have to play Guess Who against the survivors using features like zombie blending to act like a NPC in hope they will let their guard down. -The maps and settings look really good & are well optimized. -The free comic included with the game is a nice addition. Cons: -Movement is slow and sluggish. It would be more fun to have unlimited sprint with maybe the downside of sprinting having a 25% chance of alerting a horde every 30 second and some zombies sprinting faster. -Sometimes the game will play your own footsteps sounds even when standing still or even with no nearby zombies causing confusion. -The phone is a immersive and cool idea for player guidance, but some of the hints are very vague, its easy to click away from the current objective with no easy way to review it, and you cannot "codec call" NPC's for directions, descriptions or just storytelling which feels like a missed oppurtunity. -The game generally runs well but may crash randomly at times. Being mostly abandoned, the few glitches remaining are unlikely to be fixed. -Key items nessecary to progress (like Bolt cutters and Keys), take up inventory space just like optional weapons meaning you must waste time remembering and backtracking to get your dropped weapon back. They will also magically disappear from your inventory once used meaning you cant save them for a future encounter/puzzle to save search time in a later map. 6/10. its good but could be greater.

This game... Every now and then I return to it - mostly solo - and sink in its atmosphere and pacing. The few times I've had friends to join - it was some of the best coop out there. Contagion is a zombie shooter that isn't arcady but neither is overbearingly grounded where you have to manage a myriad of extra systems like hunger, weight or temperature. It's raw, a clunky, clearly undercooked, but I'll be damned if Contagion is not one of the best zombie games I've played. And I've played the bunch: from Resident Evils and Left 4 Deads to niche ones like Terminus and Into the Dead. What Contagion lacks in comparison to most good zombie games you know, it makes up for in droves with how the 'oh shi' emergent situations that are borderline movie-like in their nature. It just gets zombies, gunplay, and atmosphere so right. The devs didn't slack on it either throughout the years: there's a ton of maps and modes with a varying degree of randomized routes that makes them very replayable. There's individual settings from difficulty to more specific things like weapon attachment scarcity (great attachment system btw) and possibility to get infected. Even minute details like whether infection spreads through any damage from a zombie or only bites. Infected players can play as zombified versions of themselves and even blend in with zombie NPC crowds to not get recognized from the bunch. Or they can become... cockroaches. Don't ask. I also don't want to say that it sometimes feel like Resident Evil multiplayer in FPS form, because it isn't. But it also sometimes feels like it.

Great game in most areas. Can get confusing and tiring if you struggle with finding items though. Also me and my friend cant get passed the union station mission. I watched 4 separate walkthroughs, each having different ending paths (after you restart the power) yet still didn't find where to go. Also the alarm that blares endlessly gave him a headache

I used to absolutely love this game, and honestly, it's still good, but unfortunately the updates haven't improved it—they've mostly made it worse. For example, in the past you could only hear zombies when they were actually very close to you. Now you can often hear them constantly even when there aren't any nearby. In my opinion, this change is especially annoying. I know it's probably meant to make the atmosphere more immersive, but it just ends up being distracting. Then there's the map difficulty, which is all over the place. Some maps are easy enough to complete solo, while others are nearly impossible even with three friends. It would be great if the difficulty settings actually made a difference, because not everyone wants to struggle through every single game. Sometimes you just want to relax and enjoy the atmosphere. Another frustrating thing is that on some maps, near the end, zombies start spawning endlessly. That can make the game practically unplayable. Thankfully, not every map is designed like that. Personally, instead of the campaign mode, I would have preferred more traditional escape-style maps, but that's just my opinion. Overall, this still isn't a bad game, but it used to be much better. It had so much potential, and I feel like the developers didn't build on its strengths to make it even better. Instead, many of the changes have made the experience worse, which is disappointing. At this point, No More Room in Hell has become a much better alternative—and it's even free on Steam. I really hope the developers can turn this game around in the future, because it genuinely deserves to be great.
