About

The B.L.O.O.M (Biotech Lethal Offensive Organic Munitions) Initiative is a fast-paced 2D top-down shoot 'em up where you pilot a drone through procedurally generated battlefields.
Your mission: gather resources, plant lethal bio-organisms, and defend your bases from relentless alien and native species on the hostile planet Shlee.
Start in a basic training drone as you learn to build, plant, and fight, then dive into intense battles as two aggressive alien factions take an interest in your expanding operations.
Upgrade your drone, adapt your strategies, and survive against overwhelming odds in this fusion of action and strategy.
Build, test, and play your own levels using the same editor we used for the campaign and survival modes. Orchestrate enemy waves and boss encounters with precise timing, script on-screen briefings and prompts, choose your biome, map size, and starting funds, and set objectives like survival, relic hunts, or kill targets. Drop in spawners, buildings, resources, and power-ups, toggle weather effects, and tweak difficulty and time-of-day—then jump straight into the game to playtest and iterate. When you’re happy, package it up and share it with the community via Steam Workshop.

Design weapons inside the game from thousands of combinations. Load existing builds, set a custom weapon for your loadout, or start fresh from built-in templates like Spiral, Laser, and Missile. Edit, rename, and manage your creations, delete what you don’t need, and jump straight back into play to test them with your custom levels - no external tools required. These too can be shared with the community.

[h1] Information / Review English [/h1] The B.L.O.O.M Initiative falls into the arcade 2D genre, developed by Trema-Coding and still in development, so bugs may still occur. [h1] Gameplay / Story [/h1] We begin the game on the planet Shlee by building a base. Of course, we have to collect resources to build it. We also play gardener and plant plants, which we also need. Oh no, not plants, but bioorganisms, which we urgently need to defend our base against hordes of aliens. But we are not alone on the planet; other factions have also settled there and want to survive. If we are discovered, the fight for valuable resources begins, and we receive visits from the others. We thus enjoy exciting and fast-paced battles where we have to defend our possessions. So we have to constantly grow and upgrade our drone into a true machine. During the quieter phases, we collect the necessary resources or harvest our organisms. [h1] Pros [/h1] + Multiple game elements combined + Construction and resource management + Exciting battles + Upgrade options + Appropriate background music + Simple controls + Good value for money [h1] Cons [/h1] - Nothing noticed so far [h1] Conclusion [/h1] The B.L.O.O.M Initiative offers a mix of different gameplay elements that already work well and leave you wanting more. It will be exciting to see what's to come.

[h1] Gameplay / Geschichte [/h1] Wir beginnen das Spiel auf dem Planeten Shlee in dem wir eine Basis errichten, hierfür müssen wir natürlich Ressourcen sammeln, um diese aufbauen zu können.

Ach nein keine Pflanzen sondern Bio-Organismen, welche wir auch dringend benötigen, um unsere Basis gegen Horden von Außerirdischen verteidigen zu können. Wir befinden uns aber nicht alleine auf dem Planeten, den auch andere Fraktionen haben sich auf dem Planeten niedergelassen und wollen überleben. Wenn wir entdeckt werden dann beginnt der Kampf um die wertvollen Ressourcen und wir bekommen besuch von den anderen. Wir kommen somit in den Genuss von spannenden und rasanten Kämpfen wo wir unser Hab und Gut verteidigen müssen. Wir müssen also stest wachsen und unsere Drohne zu einer wahren Maschine aufrüsten. In den ruhigen Phasen sammeln wir die benötigten Ressourcen ein oder ernten unsere Organismen.

This fast-paced 2D top-down shooter throws you headfirst into hordes of alien freaks just waiting to ruin your day. But don’t worry — you're armed not only with bullets and plasma, but also with some questionable biology that might just eat you alive if you’re not careful. The game absolutely drips with early ‘90s vibes — from its pixel art style and synth-heavy soundtrack to the overall arcadey energy of it all. It's like flipping through an old issue of PC Gamer, except everyone’s shooting aliens and growing murder plants. In short, this game is what happens when "Alien" meets "Tamagotchi," shaken up with a healthy dose of retro radness from the '90s. A must-play for fans of action-packed absurdity and old-school chaos.
[b]Survive the swarm![/b] [i]The B.L.O.O.M. Initiative[/i] is a throwback to the classic sci-fi shooters of the '90s, injecting otherworldly imagination into tried-and-true gaming. A retro art aesthetic and music strums the guitar of nostalgia as you fight off vociferous enemies with weapons that become more powerful the further you progress in the game. With modern features like base-building and resource management, gamers who grew up on titles like [i]Alien Swarm[/i] and [i]Warcraft[/i] should get an old-school kick out of [i]B.L.O.O.M.[/i]
Pretty cool concept, just need to adjust and add some items, music in the levels, but the ship shooting mixed with rts mechanics its very interesting, will leave my support here.
The game is cool, nostalgic and reminds me of the times of vintage space games It looks like this is something that will be downloaded en masse by fans of vintage games from time to time) I really want there to be a multiplayer) I highly recommend this game)
[h1] 前言[/h1] 《The B.L.O.O.M Initiative》是一款老式太空异星球背景的2D 俯视角射击游戏,玩家需要在指挥官艾琳的引导指挥下,在施利星球种植植物+保卫基地,面对派出外星部队、意图将咱们驱赶出星球的鸟人与蠕虫。整体场景音乐与对话间的像素头像都透露着一股仿90年代的复古风格,玩法上却是还有些融合了RTS要素的。 [h1] 内容[/h1] 游戏包含战役(剧情模式、不继承资源数值的关卡制、也不包含局外养成内容,)+生存模式+用户关卡(自定义关卡)+武器编辑器(自定义武器、但只能在自定义关卡内使用)四项功能。剧情模式目前大概20关?后续可能会支持创意工坊分享制作的关卡与武器?(EA阶段,发售于2个月前,目前仍在更新,到现在为止更新了大概26次、上次更新是一周前,具体情况可见“讨论区”作者发帖的Developer Updates) [h1] 体验[/h1] 刚进游戏我就以为这是一款RTS来着的、RTS经典的太空背景+虫子,又是建造收集又是保卫基地的,还有资源量的显示,但实际上却是WASD移动的2D弹幕射击游戏。 整体的确融合了RTS要素与弹幕射击,像是初始教程环节便会教导玩家R键采集矿物部署工厂、采集木材转化种子、种植并浇水,从而培育出火焰植物在一定程度上起到防御作用。但实际上,我感觉融合的比较浅显僵硬,除了在教程第3关的任务要求下、我个人从来没真用上过这个RTS环节。 个人感觉,虽然的确有融入一些RTS要素,但玩法之间缺乏深度融合。 一方面,游戏的射击玩法本身就具有一定挑战性。玩家操控的并非是《雷电》那种无视物理、自由平移的飞机,而是具有一定物理惯性、需要前进后退刹车、左右转向的笨逼飞机。由于导弹固定从飞机头的朝向发射、敌人也是在俯视角广阔的地图中自由移动,这就意味着玩家需要同时精确控制调整飞机头朝向和移动躲避弹幕的轨迹,操作门槛略高。(设计上也意味着后续几乎不可能加入鼠标瞄准、否则相当于0秒转向) 另一方面,游戏也没有设置什么间隙与空闲时间、来方便部署采集的RTS环节。至少就我个人而言,精确瞄准与移动始终都是件困难的差事,捡个buff回血道具都费事,更没那个功夫去顾及采集了;只能说RTS要素疑似、多少有些不相干不重要了,除了那些关卡任务要求,基本还是纯粹的biubiubiu。 应该说,本作资源用途的主要表现,只剩下个金币消耗。移动和发射导弹都会消耗金币,死亡复活也需要1000金币,金币耗尽=本关失败,整体还蛮容易产生挫败感的。 [h1]总结[/h1] 如果要给个总体评价的话,我会说以一个仿90年代复古硬核风格的作品来看,那么本作可能是合格的,只能说连难度也还原了90年代的游戏风格,但以我现代菜鸡贫瘠的抗压能力而言,多少有些操蛋了。不过,带有物理惯性的飞机操控与弹幕射击,对此感兴趣的还是可以入手一试的。 [quote]加入[url=https://steamcommunity.com/groups/GHYX]干货游戏[/url]&关注[url=https://store.steampowered.com/curator/35106417/]咱的鉴赏家[/url],不定期为大家带来游戏体验分享,也期待您来一起分享自己的游戏体验干货~[/quote]
The game is very good. It combines many elements that I like, a little bit of alien shooter, farming simulator, creepy Dune-like wormhole,... In addition to the story levels, you can create your own level to share or play with friends. Absolute recommend!!
I really enjoyed the game and definitely recommend it. It has an interesting storyline and it's easy to immerse yourself in the character. By the way, the dynamic battles are just awesome.
The B.L.O.O.M Initiative ( Gameplay ) Rating: 3.9/5 https://www.youtube.com/watch?v=0WPzmSzKaoc
As a big fan of bullet hell genre, I went into The B.L.O.O.M Initiative not knowing what to expect, and it honestly blew me away. The game runs very well. It’s rare to find something this optimized in early stages. What really makes it stand out is how it mixes classic top down shoot’em up action with base building, farming, and resource management. Sounds crazy, but it works... and it’s fun! There’s something super satisfying about jumping from bullet dodging chaos into a calm moment planting crops or setting up your base. Definitely keeping this one on my radar. If you’re into classic top down action games with base building features, The B.L.O.O.M Initiative is totally worth your time. Looking forward to how it evolves!
