This mod fixes a lot of bugs and typos while adding improvements and reworking all weapons. All guns are more realistic and perfectly balanced. The guard mode works more reliably, the accuracy penalty for standing/crouching stance has been reduced and mercs can get more levelups before they reach the levelcap. Traders have better variety of weapons available. Armor penetration of all projectiles has been reworked. === === What's new in 1.3: More than a hundred changes to weapons, ammo, mercs and traders. Full list of changes can be found in the download archive.
I need to find time to test this out. It always bugged me that the AK47 used 5.45x39 in the vanilla.
