The Perfect Engine for
Authoritative Server Games




Authoritative TPS/FPS
are the core target for BOLT.


Needs to be combined with an orchestration solution like Gamelift or Multiplay.


Battle Royale


Up to 40-50 players
this is out of the box.


Large player #s (> 50) are a challenge and require special skills with scoping.


Action Games


Authoritative action games
where the Unity Engine needs to
be available in the host.


It is worth to consider other architectures/approaches that make Unity on the server obsolete.


BOLT was inspired by several influential papers that has been written about online multiplayer (you can find a link to the papers in our documentation).

  • Tribes Networking
  • Halo Reach Networking
  • Source Engine Multiplayer Networking



Support of Four Main
Scenarios & Architectures


BOLT’s flexible architecture allows to build a variety of fast-paced game genres. Choose the architecture that fits best to your game and your requirements.


Dedicated Server


The server is dedicated and has a public IP (less connection problems with best security options).

BOLT Dedicated Server Architecture
  • Photon Cloud does not offer to host Unity Instances. Possible solutions are Gamelift (by Amazon), Multiplay (by Unity) or custom solutions.
  • Uses Unity on the server, potential stability / memory / CPU issues.
  • Best practice for Fortnite, Halo, …

Listen Server

or Client Hosted

One of the clients hosts the game, to minimize operational costs. Has its Pros and Cons.

BOLT Listen Server or Client Hosted Architecture
  • QoS may be a challenge: Host may drop-out (host migration)
  • Relayed clients have a 4 hops (client-relay-host => host-relay-client)
  • Professional solution is a dedicated server.

Two Player


Direct (p2p) connection with NAT punchthrough and a relay as fallback.

BOLT Peer-2-Peer Architecture
  • No host migration necessary. The game ends when one player drops.
  • Client cheat detection needed.

Local LAN / Wifi


A Listen Server for a LAN / Wifi with automatic host detection.

BOLT LAN and Wifi Architecture
  • Punch works.
  • Local connection = very low latency
  • Simple matchmaking



  • I got off to a rocky start with BOLT but after getting it working, I have to say BOLT is one of the smartest packages I have ever used.
  • BOLT does a great job in balancing ease of use with efficiency.
  • BOLT has saved us many hours and lots of money providing us with the ability to do authoritative servers, lag compensation, client side prediction and many other things!
  • Don’t waste your time, take a look, try it and you`ll never let it go ...
  • BOLT is hands down THE BEST networking tool you can use. End of review.
  • Works as described. Excellent support.
