Indicator & Smooth Gameplay — Xheres Steam update #271180

Following recent Xheres gameplay streams has brought enlightenment in so many ways, I've realised that some adjustments are required to be performed. Such as: Indicators of current door interaction is insufficient for some players thus added more indicators to point out double electronical lock mechanism on the gate of the "Research Facility" Level and the path to the control room can now be found by pressing "LEFT ALT" once reaching to the electronically closed gate. Resurrection mechanism for immobile zombies needed to be improved both for animation & chase situations Mid section(Hallways) of "Research Facility" level was relatively empty with regard to amount of the ammo & the weapon, obtained alongside the road. So in order to prevent boredom and bring action some combination of enemies has been added. Decoy weapon crates have been altered with ordinary ones.
