Geo-Mod 2.0
Geo-Mod 2.0 is the engine that powers Red Faction: Guerrilla.
Description
With the introduction of the second Geo-Mod engine, Volition has done away with the enviromental destruction seen in Red Faction and Red Faction II in favour of a system where all manmade structures are destructable. The only bad thing is that everything can be destructible which means that you can accidentally blow up your own hiding place sometimes, but otherwise Geomod 2.0 is a runaway success.
Editing Tools
CLOE is Red Faction: Guerrilla's primary editing tool, however it is currently not publicly available. THQ Nordic has stated that CLOE is "unfortunately very close with source assets and data", making public release much more difficult.
