The Coalition: At launch there are two major visual themes for tiles; Mining and Ventilation. The Escape Trailer and Hive we showed at E3 has examples of tiles from both themes, but the majority of unique content has yet to be experienced.
The Coalition: With Map Builder, the possibilities are endless as the community can build and share their Hives to play through the Custom Lobby Browser. There will be 4 Escape Hives available at launch, with new Hives releasing ~weekly after launch
The Coalition: In past games, the reticle bloom would determine how accurate your shots were, while in G5 - it's moved to a recoil based system, where each weapon has a predictable recoil pattern that players can learn & master.
