As mobile hardware continues to evolve, players demand deeper, more immersive experiences on their phones and tablets. At EONEvolve, an independent mobile game development studio based in Istanbul, Turkey, we view this shift as an opportunity. We design games that push the boundaries of realistic simulation and tactical action.
But how do you translate complex physics systems and addictive gameplay loops onto a mobile touchscreen? Today, we are taking you behind the scenes of our development process, exploring how we built the realistic physics in Bicycle Extreme Rider 3D and the high-octane progression system in Heat Rush: Hero Shooter.
1. Taming the Physics: Bicycle Extreme Rider 3D
One of the biggest challenges in mobile game development is simulating realistic physical forces in a way that feels organic rather than frustrating. For Bicycle Extreme Rider 3D, our physics team set out to model real-world BMX, MTB, and Fixie dynamics.
Our custom physics system calculates three primary forces in real-time:
- Tire Friction and Surface Contact: Whether you are grinding a metal rail in a city park or sliding down a muddy slope, the game dynamically adjusts wheel grip to simulate traction.
- Rider Momentum & Lean: Stunts like backflips and 360-degree spins require realistic weight transfer. By leaning the rider forward or backward, players control the angular velocity of their rotation.
- Suspension Dynamics: Landing a 50-foot drop on concrete is very different from landing on a dirt ramp. Upgraded suspension absorbs the landing force, protecting the rider from crashing and keeping the score multiplier running.
By balancing these elements, we created a simulation that is easy to pick up, yet has a high skill ceiling that rewards precise inputs.
2. Designing the Roguelite Loop: Heat Rush: Hero Shooter
While Bicycle Extreme Rider 3D focuses on simulation mastery, Heat Rush: Hero Shooter was built around a completely different core concept: progression and tactical adaptation.
In Heat Rush, players navigate an action-packed survival shooter where every run is randomized. The core loop revolves around the traditional roguelite formula, optimized for fast-paced mobile sessions:
- Tactical Weapons Customization: In each run, players acquire randomized weapon attachments and modules. Synergizing different elements—like electric ammo combined with high rate-of-fire barrels—allows players to create unique weapon combinations.
- Hero Synergy: Each hero possesses unique active abilities. Pairing the right weapon builds with a hero’s kit is essential to defeating the screen-filling bosses.
- Permanent Progression: Even when a run ends, players retain experience and materials. Upgrading your weapon mastery and permanent stat trees in the lobby ensures that you feel stronger and more capable during your next attempt.
3. The Technical Challenge: Optimization on Mobile
Maintaining a stable 60 FPS (frames per second) is critical for both precise trick execution in BER3D and dodging bullet hell patterns in Heat Rush. Optimizing these systems for a vast range of iOS and Android devices is a major focus of our engineering workflow.
To achieve this, we implement several optimization techniques:
- Dynamic Level of Detail (LOD): Cityscapes and terrain models simplify their geometry in real-time when they are far from the player, saving GPU rendering power.
- Efficient Physics Querying: We optimized our physics update loops so they run in sync with the CPU’s native refresh rates without clogging the main thread.
- Object Pooling for Particle Effects: Shooter games generate thousands of projectiles and explosion particles. By pooling these objects in memory rather than spawning them dynamically, we eliminate performance spikes and micro-stutters.
Looking Ahead
Whether we are designing realistic suspension springs or coding randomized shooter perks, our mission at EONEvolve remains the same: to craft games we are excited to play ourselves. We are deeply grateful to our community of over 250,000 players for joining us on this journey.
We are constantly working on new updates, seasonal events, and game mechanics. Stay tuned to our blogs for more developer diaries, and download our titles on the iOS App Store and Google Play Store to experience the thrill yourself!
