Design Corner #2: The Unleash System, and More!
Welcome back to Design Corner! It's been a busy stretch since our last post, and the team has been heads-down turning design theory into gameplay you can feel.
A lot of that work started with a question we kept circling back to: what actually creates depth? The definition we keep returning to is that gameplay depth is the number of meaningfully different decisions available to a player at a given moment. A row of options that all end the same way is really just one option wearing different hats.
So we turned that lens on TRU and asked an uncomfortable question: what makes each scrap type different from the others? Playing a leg should feel like a different decision than playing a torso — but at the time, it wasn't.
The Birth of the "Unleash" System
That question led straight to our flagship mechanic: Unleash.
The idea: what if each scrap type had its own innate ability you could trigger — "unleash" — at any time? At the cost of a few extra rules, every piece of scrap suddenly became a fork in the road. The abilities we landed on:
- Head — magnetize 1 scrap to this building zone
- Arm — draw 1 card
- Leg — kick 1 enemy scrap (a random enemy scrap is knocked to a random location)
- Torso — gain 1 mana
And there's a cost. Unleashing a scrap spends its color, turning it grey. Because a bot is built from four pieces of scrap, every grey piece raises the odds — by 25% each — that you'll end up with a Colorless Bot: a bot with no color set bonus at all. Do you spend that leg's kick to disrupt your opponent's board, knowing it nudges your own bot toward losing its identity? That tension is the whole point.
The results were immediate and positive. Players had real decisions every turn — which scrap to spend their limited mana on, and whether to unleash it or save it. Games produced genuinely exciting moments: a clutch last-second draw, or a well-timed Leg kick that foiled a lethal attack. Feedback and retention both climbed, and honestly, the team started enjoying our own game a lot more.
Extending Depth to Color
The same thinking carried straight over to color. In Design Corner #1 we introduced the color set bonus — the innate buff every bot inherits from its color. Together, Unleash and the color set bonus mean the scrap you play and the color you commit to are now two separate, meaningful axes of strategy: what your bot does, and how you got it there.
Designing the Factions
With those foundations in place, the next challenge was scale: designing full loadouts — cards, powers, and abilities — for a roster of factions, each with a personality and playstyle of its own. Since there's no faction limit in a deck, they also had to combine in interesting ways.
Our approach: make each faction strong at one path to victory and lacking in another. TRU sits on a rock-paper-scissors core — Attack, Commit, and Stall — so we could safely let a faction spike in one of those directions as long as we baked in the matching weakness. From each faction's theme and virtue, we'd brainstorm hundreds of card ideas, then hold every one to the classic Timmy, Johnny, and Spike test: is it exciting to play (Timmy), rich in combo potential (Johnny), or cleanly useful — without simply outclassing another card (Spike)?
All told, that's roughly 150 cards — about 30 per faction — spanning ultimates, powers, action cards, and faction-specific abilities.
A Playtesting Story
Design on paper only gets you so far; the table is where cards live or die. One example: we made a Green card that let you draw a card for every poisoned bot your opponent had. On paper, it combos beautifully with Green's poison identity. In practice, it flopped.
For that condition to pay off, you needed to have built a Green bot with its color set bonus, attacked with it, and had an opponent's bot survive that attack — a board state that, given our game's pace, only showed up once or twice a match. The rest of the time, the card sat dead in hand.
The fix was a pattern we now reach for often: either retie the effect to something more frequent (say, draw for each Green bot you control), or give it a weaker but reliable secondary use (draw for each poisoned bot, or draw the top card of your discard). Situational power is only fun when the situation actually shows up.
From the Playtests
During a recent internal session, one of our long-time players put it better than we could:
"The Unleash system finally made me feel like Two Robots had esports-level depth. I wasn't just dropping scrap anymore — I was constantly debating whether to unleash an ability or hold it for later. That tension is what competitive games live on."
That's exactly the kind of decision-making we set out to create.
