Incursion Red River Hotfix #1.4.0.1 Changes Bot Grenades and Solo AI Scaling

Incursion Red River Hotfix #1.4.0.1 adjusts bot behavior, fixes mission issues and adds changes across weapons, weather and stability. Solo raids now respond to the AI count multiplier, and bots throw grenades less accurately and wait longer before throwing one after spotting a player. The Steam changelog also flags a visual issue affecting RTX 50-series GPUs. The hotfix follows November 4 Update 1.4.0.0, which added the Outskirts map and rebuilt the RED:FOR AI system.

Other player-facing changes include separate stats for 9×39 SP-5 and BP ammunition, rebinding for quickslots, and new volume sliders for the Mission Handler and enemy voices. The update also reduces video memory use, particularly on 8 GB cards.

Incursion Red River Hotfix #1.4.0.1 Patch Notes

Known Issues

• Red outlines, light rays or discolored foliage on RTX 50-series GPUs: this comes from an NVIDIA driver problem since Update 1.4. Rolling back to driver 617.42 with a clean installation has fixed it for affected players so far. Step-by-step instructions are in our pinned thread: Workaround: red outlines on RTX 50-series GPUs. We have reported the problem to NVIDIA and are supporting their investigation.

AI

• Fixed the AI count multiplier having no effect in single player. It now scales the number of bots in solo raids as well.
• Bots throw grenades less accurately by default. Grenade accuracy can now be adjusted in the AI settings.
• Bots no longer throw a grenade the moment they first spot you. They now need to be in combat for a little while first.
• Bots call out “Taking cover” much less often.
