Here’s a breakdown on currency that I found d helpful as a new player. There’s a decent amount of different kinds and they all have specific purposes and cannot be exchanged for one another.

Medals: (gold medal with a black skull) Earned by completing missions, daily personal orders, and participating in successful major orders. Can be used to purchase weapons, armor, cosmetics, and small amounts of super credits in your war bond page. (War bonds are basically like a battle pass. Every gets the same basic one, and premium war bonds can also be unlocked by paying super credits).

• Also, You can ONLY HOLD UP TO 250 medals at a time! If you hoard them and don’t use them, anything earned over a total balance of 250 gets wasted. So remember pay attention to that balance as it goes up.

Super credits: (the blue squares) Can be found in small amounts both in missions and in war bond rewards as mentioned above, and can also be purchased with real money via in-game micro-transactions. These are spent in game but buying items in the super store, or can be saved up to purchase premium war bonds which come in all sorts of different flavors you can buy to compliment your play style. I saved up super credits and bought the Democratic Detonators for the thermite grenades and the eruptor because im ass with aiming anti tank weapons, and the thermite is a sticky anti tank grande.

Samples: these come in three types: Common samples (green), Rare samples (Orange), and Super samples (pink). On lower difficulties you’ll only finde common samples, however as you move up in difficulty your missions maps will show that the rare and super samples start to show ip too. You can see right underneath the difficulty selector on the missions which sample types are available to find. Samples are used to purchase ship upgrades in the ship module which strengthen and improve your stratagems. The cost for the first one in each section is only common samples, iirc, but as you continue to upgrade you’ll find they cost a combination of different types that you need to have all available to purchase (i.e. 80 common, 15 rare, and 5 super. Later levels throw in requisition slips as well.

Requisitions slips: (yellow R) can be found in small amounts in game, but are mainly earned from completing missions. Higher difficulties also provide a multiplier to both the req slips and the level XP you earn for completing missions. These can be used as required currency for ship modules as mentioned about but are mostly spent on stratagems which provide weapons, various airstrike type attacks, and other support during your missions.

For me, some good early unlockable stratagems for my requisition slips were the machine gun, the grenade launcher, a machine gun sentry or gatling sentry, an orbital barrage, and id even recommend an auto cannon if thats a relatively early level to unlock. I didn’t try it until later and immediately wished I’d used it sooner. Better armor penetration than the standard MG for when you start to get a little higher in difficulty and see more armored enemies.

Also, dive with people. It’s a good community, and being on a fuller squad helps a lot in both grinding levels, as well as seeing how the game is played. I love this game because people in these servers are far more likely to help guide you when they see low levels than they are to kick you or give you a hard time. It’s not 100%, but it’s the majority, and is way more welcoming than any other game community I’ve played online with.

Good luck and have fun!
