About Incursion Red River
Incursion Red River is a first‑person action shooter set in a destabilized Vietnam. The February 2026 Patch 1.3 adds Act 1 of a three‑part story, a new map called Delta, extreme weather, safe‑house upgrades, player leveling, and an overhauled economy.
The update also brings a reworked AI, new boss Monstera, additional weapons, grenades, vaulting/mantling, and an in‑game VOIP system with realistic occlusion, while the engine moves from UE 5.4 to 5.6 for better performance.
01 / THE GUIDE
Campaign Act 1
Act 1 introduces 23 missions voiced by Jane Perry, forming the first segment of a three‑act campaign. The missions are placed across the new Delta map and the reworked Quarry and Bunker locations, providing a narrative core for solo or cooperative play.
Progression in these missions ties into the new player‑leveling system and safe‑house upgrades, rewarding players with loot and access to additional in‑raid events and side quests.
- Complete early side quests to unlock additional in‑raid events that appear later in the act.
- Check the safe‑house upgrade menu after each mission to see new options that become available.
02 / THE GUIDE
New Map and Extreme Weather
The patch adds the Delta map, which features rain and thunderstorm weather systems. These conditions affect visibility and ambient sound, creating tactical considerations for movement and engagement.
Improved lighting across all maps works together with the weather effects, and the UE 5.6 engine upgrade ensures the visual and audio changes run smoothly in both single‑player and multiplayer sessions.
- Use rain‑induced sound masking to approach enemies from unexpected directions.
- Adjust scope brightness when playing in thunderstorm conditions to maintain target clarity.
03 / THE GUIDE
Safehouse Upgrade System
A new safe‑house upgrade system lets players improve facilities that support resource storage and equipment repair. Upgrades become available as players level up and complete missions.
These upgrades directly influence the amount of loot that can be stored between raids and reduce the time needed to repair weapons, affecting overall deployment efficiency.
- Prioritize storage upgrades if you plan to collect large amounts of loose loot.
- Upgrade repair stations early to keep weapons functional during longer raid chains.
04 / THE GUIDE
New Weapons and Grenade System
Patch 1.3 introduces several weapons, including the SR‑25, Galil Ace 2, M9A3, Saiga 12, Sig Sauer MPX, and Norinco CQ. Each weapon can be customized via the Gunsmith table, allowing swaps of barrels, handguards, foregrips, stocks, sights, and magazines.
A grenade system has also been added, giving players an additional tactical tool for clearing rooms or creating cover, while the overhauled recoil and stats affect handling across all firearms.
- Save multiple Gunsmith presets to switch quickly between close‑quarters and long‑range configurations.
- Experiment with different grenade types to find the most effective use in tight corridors.
05 / THE GUIDE
Economy and Resource System
The economy has been overhauled with a new resource system, a reworked Black Market, and markable resources. Players can collect loose loot and mark valuable items during raids for later retrieval.
A repair system allows damaged gear to be fixed at safe‑houses, and the vaulting/mantling mechanic expands movement options, both feeding into the updated economic loop.
- Mark high‑value resources during a raid to prioritize them when looting after combat.
- Repair weapons at safe‑houses before heading into the next operation to maintain combat effectiveness.
