About Protolife

15 years since the first colonization parties landed on Gagarin-5. 15 years of tedious yet satisfying work on making this planet our home. I miss these years now.
It all happened in mere days. The corruption spread across our lands, waves of crimson doom washed away our mushroom farms, and giant worms devoured our cities. As far as I know, only few thousands of people were able to escape into the emergency bases. Now the thing.. is dormant. It sleeps during the day, and grows only slowly over the night, filled with tumors, blights and rolling, nauseating pink lights.
This small opening seems to be our only chance to fight back, to clean the planet. And we are sure to take it.

Gameplay


Stand to defend a distant human colony against the growing lifeform that devours everything in its wake. Build complex defenses from the simplest element possible – a single block, save few remaining settlements and clean the planetary surface from the corruption in this original tower-based RTS. Initially built for a Ludum Dare 38 game jam, it was completely redesigned, got a graphics update, tons of new content, but still works around a simple idea: build towers from blocks, contain the enemy, survive the night onslaught and strike back.


Key features

  • Unique approach to building process: Every tower is constructed from patterns of simple blocks. Build your defense grid piece by piece the way you like it, upgrade, combine, optimize space and resources to survive against the overwhelming odds.
  • An enemy unlike usual RTS adversaries: Growing, living entity designed to exploit every small weakness in your defense. The more space it takes from you, the more powerful it becomes.
  • Freedom of strategy and flexible defense perimeter: Go for quick low-tier tower rush or bunk with well-defended artillery posts, then collect your blocks and rebuild the defenses on the spot — just mind the free space and resources left.
  • Direct control over the builder: Or two? Dynamically switch between several battlefronts and dominate over the enemy.
  • Over 30 levels with variative gameplay and win objectives.
  • Random missions generator with an adjustable difficulty level and special rewards.
  • Custom towers editor where you can construct your own powerful weapon.
  • Remappable keyboard or gamepad controls. Please note that the game was not designed for mouse control.

Very fun and surprsingly intricate. Very nice blend of tower defense with a little action: while no level requires it too much you can always go faster and try to win even the timed missions early with some surprisingly intense active play.

This has a similar feel to Creeper World.. If the creeper was actually as menacing as it's said to be. Like the infection does *not* know the word chill. Jokes aside, it's a solid little game. Here's for the pro and cons : + Simple to pick up gameplay loop + Very unique style, building is done in a very unique way! + Great enemy variety, it's usually an issue with these games, but not here, plenty of unique threats to have + Great tower variety, there's just about anything, they're not all born equal, but, most of their own usecase + The pixel art style works pretty well, and it looks fairly decent, plus there's some nice ideas done with it, like the trail of blood being left by enemies eventually reveals the path the enemies take ~ Difficulty is pretty high. I'm managing to get through the campaign without much issue, but I'm well versed with similar games, and I've got some good keyboard dexterity (See negative about controls below) ~ Mission pacing is fast. Honestly, after playing Creeper world, it's a great change of pace from the very slow paced mission, but I can imagine that will very much stress people out, don't play if you don't like timed missions, because…

This is basically "Dead or Night" map from Starcraft 2 in standalone game but with only tower rush by playing as armored 'Probe', A perfect mixture of Tower Defense with RTS element which hard to see these days. The way to setup desired turret or various fortification is pretty unique, fun to play and also simple to understand. It's sound like become alchemist while setup each turret. The campaign progression difficulty, while easy as first, over around half of the campaign, it's hard. the game require you to be active for the most of time, just like ordinary RTS game which it's fine by me. (it's easy and fast to restart tho, so I don't mind if it's needed) there are some tower customization part with randomize round of challenge to purchase the part for the endgame content, which it's can prolong my playtime when all campaign mission is finished (include NG+) and buildup my own tower is fun, but still. over Risk Level 5 challenges without custom tower is brutally hard, some are almost unbeatable or require more than 10 times restart. most of the challenge require you to act "very" fast in order to soften impossible swarm of enemies, which it's too hard without very powerful cu…

Protolife is an experimental strategy game developed and published by Volcanic Giraffe that blends tower defense mechanics with real-time strategy and creative construction systems. Released on Steam as an indie project, the game stands out for its unusual design philosophy, encouraging players not just to place pre-built defenses but to construct their own towers using modular components. The result is a strategic experience that places heavy emphasis on engineering, planning, and adaptation while fighting back against an ever-expanding alien ecosystem. Rather than simply reacting to enemy waves, players are tasked with designing and maintaining a dynamic defensive infrastructure capable of surviving a hostile world. The game is set on a distant planet that humanity attempted to colonize but ultimately lost to a mysterious biological force known as “proto-life.” This alien organism spreads across the landscape like a living infection, consuming structures and transforming the environment into hostile territory. Entire colonies have been wiped out as the organism grows uncontrollably, leaving only a few defensive installations and automated systems behind. The player assumes the r…
