About 100th Bug Brigade

100th Bug Brigade is an accessible, story-rich, tactical, team-based roleplaying game featuring very cute bugs in a very uncute time.
Expected playtime: 1 hour.

Don't let the Robugs win! Lead the underdog forces of the 100th Bug Brigade and defend your home tree! Though the battle is dire, hope rests with you!

Clever tactics utilizing each member's unique active and passive abilities can turn the tide of the war.
Possess your enemies, throw your allies, or put your life on the line for an ultimate attack. Use the ability tooltips to exploit every aspect of your team's abilities to overcome the odds.
Manipulate the battlefield to your advantage (or the Robugs will!).
Dynamic battlefields altered by your actions and the story combined. Retake conquered areas, revealing new bosses and environmental mechanics. But beware! If the Robugs can't chomp on you- they'll chomp on your defenses.

Understand the emotions of the 100th Bug Brigade to discover hidden strengths and weaknesses.
The Robugs may not have feelings, but your team does. Use clues from their dialogue on the battlefield to uncover strategies against the unfeeling Robugs. But if the Robugs don't feel, what motivates them...?

You are not alone! Though you are their leader, the 100th Bug Brigade will serve not just as your soldiers, but also your advisors during battle.
New to tactics or roleplaying games? Don't worry. The 100th Bug Brigade, and the development team behind them, have got your back. We designed the game to be accessible to new players, while retaining the depth of strategy that veterans expect.

100th Bug Brigade is a surprisingly thoughtful tactical RPG that I liked much more than I expected. The premise sounds adorable because I am commanding a group of cute bugs, but the story quickly becomes much more serious as I try to defend their home from the invading Robugs. I enjoyed that contrast because the friendly visual style hides a surprisingly emotional story. The combat is turn based and focuses heavily on using each member of my team properly. Characters have different active and passive abilities, and I have to think carefully about positioning if I want to survive the tougher encounters. I especially liked the strange abilities that let me possess enemies, throw allies or sacrifice health for powerful attacks. Those options give the battles more personality than a standard tactical RPG. The battlefield itself can also change during the story. Areas can be retaken, new environmental mechanics can appear and the enemies can attack my defenses when I cannot reach them directly. I liked this because it means I am not simply fighting on identical grids every time. The environment can become part of the strategy rather than just a background. The story is another major …

Really endearing art, music and story. It's short but effective, and I do like how it worked on an AP system as opposed to something like Fire Emblem, where most actions are equal. My only complaint is that the controls are a bit superfluous-- I feel like most of those different buttons could have been condensed down into just a small handful. I felt like I was clicking much more than I'm used to for games in this genre.

No Steam achievements at all, which is disappointing for a tactical RPG with multiple battles, characters and story progression. Even with the game's short one-hour length, there were plenty of opportunities for simple achievements for completing battles, defeating bosses, using different abilities or finishing the story. It's a free game, but adding even a small achievement list would have given achievement hunters a little more incentive to play through it.

A truly charming game with gameplay that's fun yet I personally found it not hard enough (which mind you isn't necessarily a bad thing). You can really tell this game was made with love and passion and I'd love to see more from this world. Highly recommend if you're looking for a around 1h experience that's worth your time

This game is extremely charming. I'm always of the opinion we can have more insect related games. There are few minor bugs such disappearing movement titles. Regardless, I deeply enjoy worldbuilding, characters, and art style. I would love to see more of this world.
