How will SS: Sentinels differ from the original?

Sentinels will have several distinctions from the original.
Major distinction will reside in team management system. “Sentinels” is not a governmental organization and it means that combat equipment and weapons are not a free stuff anymore. Money makes the world go round now. As a leader, you manage resources of your group, raise money through specific missions, hire better mercenaries, and buy new weapons, equipment and even valuable information sometimes.
Furthermore, combat arsenals will be supplemented with new weapons and prototypes, developed by the end and immediately after the war. These will include such models as AK-47, Korobov TKB-408, Sterling SMG, RPD machine gun and some others. Their improved range and/or damage parameters will eventually present new tactical possibilities and additional firepower to your squad.
We’ve also implemented weapon reliability factor into the game, in order to add an element of surprise and make the gameplay feel more real. Certainly, it doesn’t mean your firearm will break down or jam at every step now and then. It will be well balanced...
