Movement, Enemy bots, and Combat Fixes Update — Ghost Battalion Steam update #1549155

Change Log: • Improved player movement — items on the ground no longer block or halt player movement when they can’t be picked up. Mechs now move freely through dropped items as well, preventing unwanted stops during movement. • Rebalanced enemy bots accuracy — body shots are now significantly more common than headshots, reducing unfair one‑shot kills from enemy bots. • Disabled self‑damage from weapons — players can no longer accidentally shoot themselves and die. • Single‑player loadout improved — players now start the first Campaign mission with a machine gun, and the rocket launcher is available in the Armory zone as a pickup for first‑time players. After the first run, the rocket launcher must be equipped from the supply crate as usual.
