About Project Hastur

PROJECT HASTUR creates a unique challenge by combining elements of 3D tower defense and real-time strategy with biological evolution. Fight against alien Proteans that evolve - using biologically accurate models of evolution - to overcome the player’s defenses.

Each creature you will face has its own unique genome controlling its abilities, behaviors, and appearance. Those that make it the furthest and do the most damage to your defenses have the most offspring you will have to defeat in the next generation. The result? Evolution responds to the player’s strategy and makes every playthrough a unique experience.

Use four upgradable turret classes, plus airstrikes and combat robots, to fight against the Protean invasion. Make strategic decisions about which turrets to build, when to upgrade them, and where to place them on the hex grid. A well-timed airstrike can change the flow of the game, but you'll have to wait before you can use it again. Unlock powerful upgrades for each turret class as you move across the Nyx system. As you play, the Proteans evolve new weapon resistances, behaviors, and movement capabilities to better destroy your defenses.

In CAMPAIGN MODE, battle through a series of maps as a military defense commander to protect the planet Nyx from the ever-evolving threat of the Proteans. Unlock weapons and upgrades and use them to fight against the Protean swarm and learn about the mysteries of Project Hastur.

In EXPERIMENT MODE, choose any map, tweak the parameters, and play infinitely to see what you can evolve. Change the number of creatures and the parameters of evolution, make your turrets invincible, or crank up the biomatter and experiment with the most powerful turret upgrades. Experiment mode lets you experience Project Hastur your way.

Игра Project Hastur оставила после себя смешанные чувства. С одной стороны – интригующий сеттинг, вдохновленный мифами Ктулху, и гнетущая атмосфера, которая действительно держит в напряжении. Визуально проект выглядит вполне достойно, особенно учитывая его инди-статус. Звуковое сопровождение, в частности эмбиент, отлично дополняет общее чувство безысходности и надвигающегося безумия. Однако, игровой процесс оказался несколько однообразным. Исследование локаций и решение головоломок, хоть и связаны с лором, быстро приедаются из-за повторяющихся механик и недостатка разнообразия в задачах. История, хоть и представляет интерес за счет мистики и загадок, подается довольно фрагментарно и порой сложно уловить общую картину происходящего. Оптимизация также оставляет желать лучшего. Наблюдались падения FPS даже на достаточно мощном железе, что негативно сказывалось на общем впечатлении от игры. В целом, Project Hastur – это неплохая попытка окунуть игрока в мир лавкрафтовских ужасов, но требующая доработки в плане геймплея и оптимизации. Можно рекомендовать фанатам жанра, но с оговоркой на недостатки.

A well thought out and decent tower-defense game. The conceit here is that the monsters adapt based on your strategies, and it really feels like it works. As a result, it can get pretty tough at times, but that's part of the fun. I felt the controls were a little lacking, there were times when I felt I had trouble targeting the spot I wanted, and it isn't always clear which path the creatures can or will take, but nothing that really kills the fun, it;'s all about learning. Expect to have to try a few times to pass some levels! For hardcore TD lovers though, this is darn good, with nice graphics to go with it.

this game is very fun, it is also easy too run. And if you love tower defense games that get progressively harder, this game is for you
Not recommended Dec 24, 2023
just not really that fun after the first couple missions, way too long to get any real upgrades

Boltgun 2 price: buy the sequel, or the cheap first game?

The Boltgun 2 price has no cheaper route on launch day — our record shows one listing, unmoved since September. The first game is the bargain, but a smaller one than it was.
