Ace Combat 8 Fast MRP Farming: Best Missions to Grind
For fast MRP in Ace Combat 8, sortie into Mission 16 for about 82k on Elite or 98k on Ace in roughly three minutes, or run Mission 27 Megafloat using the Stand-Off Dispenser (SOD) or LACM to eliminate target clusters efficiently across the map.
Why MRP Matters
MRP is the currency you spend on the Aircraft Tree, and the endgame is expensive. The three top-tier aircraft each cost 550,000 MRP, the post-campaign FA-36 and EA-36 each cost 750,000 MRP, and the X-40 Nightmare costs 1,000,000 MRP. Grinding efficiently means picking a short, repeatable sortie rather than replaying long missions for a mediocre payout. The routes below are the ones veteran players consistently recommend.
| Mission | Difficulty | Approx. MRP | Approx. time |
|---|---|---|---|
| Mission 16 | Elite | about 82k | roughly 3 minutes |
| Mission 16 | Ace | about 98k | about 2:30 to 3 minutes |
Mission 16: The Short Repeat
Mission 16 is the workhorse for players who want quick runs. On Elite it pays about 82k MRP in roughly 3 minutes, and bumping it to Ace raises that to about 98k MRP in about 2:30 to 3 minutes. Because the sortie is short, you can string several back-to-back repeats in a sitting and stop when you have enough, which makes it the most flexible option.
Mission 27 Megafloat: SOD and LACM Strategy
Mission 27, the Megafloat sortie, is a favorite for players who prefer cluster-clearing over pure dogfights. The community consensus is to bring either the Stand-Off Dispenser (SOD) or the Land-Attack Cruise Missile (LACM). Deploying SOD on platforms like the Super Hornet or F-35 allows you to delete an entire platform spoke in a single pass, while LACM provides the range needed to snipe reactor pillars while safely avoiding defense fire. Clearing the platform spokes cleanly allows completing the sortie in three to four minutes with massive score payouts.
How to Fit Grinding Into Your Run
Do all your Assault Record cleanup before you start pure MRP grinding, or you will replay the same missions twice. If you are chasing the 31 conditional named aces, knock those out on Veteran difficulty first, then switch to these MRP routes to fund the Aircraft Tree. Remember that the X-40 Nightmare only unlocks after the campaign and requires owning an F-22A, F-35C, or Su-57, so save for one of those three first.
Pick a Route That Matches Your Goal
Choose the route by what you are saving toward, not by raw numbers alone. If you are still early in the campaign and want steady, repeatable income, Mission 16 on Elite or Ace is the most flexible because each run is short and you can stop whenever you have enough. If you are building toward the 550,000-MRP top-tier aircraft that gate the X-40, the larger lump sums from Mission 29 on Rookie get you there in fewer sits.
Mission 27 Megafloat sits in between: a longer sortie than Mission 16 but a dependable payout when you bring the SOD. Whichever route you pick, keep the run clean and fast, because Ace Combat grades reward completion speed and the same discipline shortens the missions you are replaying anyway. Across the full campaign this saves a surprising amount of time, since the Aircraft Tree asks for several million MRP in total and every minute shaved off a farming run compounds. If you are undecided, start with Mission 16 on Elite and graduate to Mission 29 on Rookie once you are comfortable.
Why These Three Routes
These routes come from veteran players who tested repeatable, short sorties. Mission 16 is the flexible repeat because each run is short; Mission 27 Megafloat rewards bringing the SOD to a dense cluster; and Mission 29 on Rookie is the big payout when you need a lump sum. None of them requires a specific endgame aircraft, so they work even early in your first campaign, which matters because the X-40 Nightmare waits until after the story is done.
The point of grinding is to fund the Aircraft Tree, and that tree asks for several million MRP across the top-tier aircraft and the post-campaign purchases. A disciplined short-run approach beats chasing a single long sortie, because you can stop whenever you have enough and adjust to what the next mission needs.
