I remember playing the #OperationFlashpoint demo in 2001 and noticing attack vectors for entire battalions on the map. My imagination ran wild—was the game really that big?
Let’s talk about how we invent forces to create the illusion of a large war… and to run wargames! (1/11)
Wargaming—whether through board games or computer simulations—is used by real militaries and governments to play out scenarios, test strategies, and predict outcomes. It prepares armies for all eventualities. Why couldn’t it prepare game developers too? (2/11) Image
It’s during #Arma3 development when we started playing wargames for research. For each stage of the campaign, we discussed how the conflict could unfold. @IvanBuchta then prepared maps showing the movement of main forces, even if you could never encounter them in the game (3/11) Image
Image
This groundwork proved invaluable when developing DLCs like Laws of War and Tanks, which portrayed the East Wind campaign from different perspectives. Thanks to our wargame preparations, we had a clearer picture of what was happening across the island. (4/11)
But it’s not just about knowing where the armies are; it’s also about understanding what they consist of. That’s where the Order of Battle (ORBAT) comes in—a diagram showing the types and sizes of forces within a military unit. The example below shows the Dutch Army 🇳🇱(5/11) Image
When planning a large-scale multiplayer mode for #Arma3 (which was eventually canceled), the multiplayer designer sketched out the ORBAT of the ideal military unit for the operation. He drew on his own military experience, as it was none other than @rocket2guns! (6/11) Image
Later on, fascinated by these diagrams, I implemented an in-game ORBAT viewer as a side project. The illusion we’d used since Flashpoint became interactive, with map markers linking to carefully analyzed previews of whole armies. (7/11)
I originally made it to give players a better idea about what forces are involved in campaign missions. What I didn’t anticipate is how informative it would be also for us. (8/11)
For example, plotting the Altis Armed Forces (modeled after the Maltese army) made us aware of how tiny the army is: a thousand men, a dozen tanks, a handful of helicopters. This made mission designers more cautious about casually sending precious vehicles against players (9/11) Image
Once we had the viewer, we realized we could give some units a custom identity. That’s how the US invasion force became the 111th Infantry Division, and CSAT’s army was named the Griffin Regiment. Shoulder insignias helped reinforce this in-game. (10/11)
Wargaming maps, orders of battle, unit identities, those are just some of the tools we use to plan authentic conflicts. Only a fraction of this preparation ends up in the game, but it's as important as it's fun to do. Expect us to continue this tradition in the future ;) (11/11) Image

🌊 There's another authentic gameplay effect of the moon I've seen only in @ArmaPlatform—tides. Ever since the original #OperationFlashpoint, the sea would go up and down based on where the moon was in the sky. But not anymore since #Arma3. Why? A short thread🧵(1/7)
All official terrains in OFP, #Arma1, and #Arma2 simulated tides. The sea level would go up twice a day by more than a meter, and then recede again. Harbor piers that were previously almost submerged would suddenly be taller than most boats. (2/7) Image
While Arma’s #RealVirtuality engine still supports the feature, we turned it off in official #Arma3 maps. As the game's fidelity increased, variable sea level caused issues with new visual, audio, or physics features. (3/7)

🌕 It's the full moon tonight. But in many video games, it's magically the full moon every night!

Why is it so difficult to portray the lunar cycle realistically? And what are #gamedev tricks to make moon phases appear accurate? A thread 🧵 (1/16)
First, if a game doesn’t simulate a day/night cycle, devs can choose any moon phase that suits their artistic or practical purposes. It just so happens that levels in @Hitman, #Uncharted4, or #ObraDinn take place during the full moon. @LifeIsStrange even during two! (2/16)

Permanent full moon is a common fixture even in open-world games that do simulate the passage of time, ranging from big-budget titles like #HorizonForbiddenWest, #MGS5 or @GhostRecon, to indies like #PacificDrive. But why? (3/16)

As I'm starting to introduce my son to navigation in nature, I realized a lot of my knowledge comes from playing Bohemia games! A thread (1/15) 🧵 Image
📍Most open-world games simply show your exact position on the map, like GPS in your phone. It's convenient, but it teaches you nothing. Arma on default difficulty used to do that for decades, but not anymore in Arma Reforger. So how else can you find your way? (2/15)
🗺️ Map grid is a useful tool for that. For example, when you carry a GPS in your inventory in Arma 2, it tells you your coordinates. You still have to find the grid square in the map, reading first right, then up (picture from @Dslyecxi's handy tutorial: ) (3/15)ttp3.dslyecxi.com/basic_infantry…Image

#ArmaReforger doesn't just have a photo mode, it has #Armavision!

Let me share a few tips with you.
You can access #Armavision anytime during the game from the pause menu.

Please keep in mind that if you don't have Game Master rights, camera movement will be limited around the player.
Use camera Properties (V on keyboard, hold View on gamepad) to customize scene overlays and post-process effects.

Before taking a screenshot, don't forget to hide the interface (I on keyboard, Right bumper+Dpad up on gamepad).
