About Invention 4
Dorian carries certain types of weapons with him: Knife, Shotgun, Grenade Launcher and Kalashnikov.
The knife is good at close range, the shotgun at medium range, but requires reloading.
The grenade launcher creates a large explosion and is capable of hitting multiple enemies at the same time.
The machine gun is a universal weapon, but its ammunition is extremely limited.
Using the tactical superiority of each weapon, defeat the hordes of monsters and bosses!

First off let me just start off by saying that i love Zombie games and that i saw this game for $3.99 and thought what the heck, i'll give it a try. I love the concept of the game and the visuals are good. I wish that your character could jump tho and that he had a flash light especially on the cemetery map. some areas are very dark but i like the overall atmosphere of the map. The one thing about the game that i thought was funny was how is your Melee attack with your knife more powerful than your guns. i can shoot a zombie like 5-6 times before they fall but only 2 hits from the knife and their dead excluding special zombies and bosses. However, i will give this a game a thumbs up because i do like the concept of the game and i have fun playing it. This game has the potential to be a great game with a few minor adjustments.4 found this helpful
If you want this game, then stop, think and wait for the discount. I've already bought it and tried it out. The game didn't impress me much. There are a lot of interesting solutions, but the game is too damp and it spoils the first impression4 found this helpful
Killing zombies is good, but it's not what I wanted, and I don't want to go any further. She doesn't look like Resident Evil 4 at all and didn't impress me. Since I'm a fan of a slightly different direction. By the way, I was surprised that the game was made on the Falco Engine.3 found this helpful
A good shooter with puzzles, in the style of the 2000s. But it's already 23 years old, I think the game will find its fans.1 found this helpful
The game is good for now. An interesting indie-action game that is really funny. As being an indie game that’s not bad.1 found this helpful
Invention 4 developed and published by Cow Games and Falco Software is a modest first-person shooter that embraces a familiar post-apocalyptic formula, delivering a straightforward experience centered on survival, combat, and light objective-based progression. Set in a world devastated by a viral outbreak, the game places players in the role of a hardened mercenary escorting a key companion through hostile, infected territory. While the premise is recognizable, it serves primarily as a backdrop to the action rather than a deeply explored narrative thread. The gameplay is rooted in traditional FPS design, focusing on moving through linear environments while engaging waves of enemies. Combat is immediate and uncomplicated, offering a small selection of weapons that cover basic roles such as close-quarters damage and crowd control. Switching between these tools adds a bit of tactical consideration, but overall, the mechanics remain simple and accessible. The shooting feels functional, allowing players to progress without much friction, though it lacks the refinement and feedback that would make encounters more impactful. Over time, the repetition of similar enemy behaviors and encoun…
