Premium in Xterium speeds up progress and saves time, but it’s easy to overspend here. The game features two different types of “premium”: a permanent VIP subscription and flexible boosters—bonuses that you customize to your needs. Below, we break down what they offer, their durations, and what you shouldn’t overpay for. The durations and benefit percentages are taken from the game’s code (verified); the tips come from the community.
Where did this guide come from? The VIP durations, benefits, and accelerator compositions are taken directly from the game code (War of Alliances universe). The “what to get first” tips are recommendations from players on the player wiki and this forum thread. These are player tips, not official instructions; for exact numbers, check the encyclopedia and the game itself.
Step 1. Understand the difference: VIP and accelerators
There are two different things in the game that are often confused:
- VIP is a subscription service. As long as it's active, you'll enjoy benefits every day (see Step 2). You can purchase it for 1, 3, or 12 months.
- Flexible Boosters are individual bonuses (faster resource collection, more expeditions, more science, etc.) that you can enable one at a time to suit your playstyle. This isn't a subscription—you put together the set you need yourself.
You can choose either one or the other. VIP provides a “background” of ongoing conveniences, while Boosters offer targeted enhancements for what matters most to you.
Step 2. What Does VIP Offer?
VIP is a package of ongoing perks. As long as your subscription is active, you’ll receive the following (from the game code):
- Antimatter every day (this is the game's premium currency).
- A free daily bonus refresh and additional daily promotions.
- Unique VIP avatars and the ability to change your nickname color in chat.
- The right to post in the general chat while in Vacation Mode.
- Increased storage limit for intelligence reports and sales limit for the fleet/defense.
In other words, VIP is primarily about comfort and daily antimatter, not a direct “economic boost.” If mining numbers are what matter most to you, check out the accelerators (Step 4).
Step 3. Select a VIP subscription period: 30, 90, or 365 days
VIP subscriptions are available in three terms, and the longer the term, the better the value per month. The game’s code is designed to provide a direct benefit for longer terms:
| VIP Term | How much is that? | Benefit (from the code) |
|---|---|---|
| 30 days | 1 month | without a discount |
| 90 days | 3 months | 18% profit |
| 365 days | 12 months | 35% profit |
The price depends on your region and payment method, so please check the game for specific amounts. But the rule is simple: a one-year VIP subscription is significantly more cost-effective per month than a one-month subscription. If you plan to play for a long time, a longer subscription saves you the most money.
Step 4. Flexible accelerators—adapt them to your style
Flexible boosters are individual bonuses that you activate one at a time. In the game, they are divided into two groups:
- Under "Production and Development" — increased mine output, increased energy production, and increased scientific research, plus contract funds and rewards, and faster construction queues.
- For expeditions and battles: more groups in expeditions, more simultaneous sorties, higher rewards in combat sectors (Ruins, Hostile), and weakened enemies in expeditions.
Each booster is purchased based on its power (level) and is billed on a “per day” basis—that is, you pay for the number of days it will be active. That’s what “flexibility” means: you don’t have to buy everything; just choose what helps you achieve your current goal.
Step 5. What to Spend Money On First
The community's advice is not to spread yourself too thin, but to focus on what gives you the most bang for your buck in your game:
- Develop your infrastructure and economy → use boosters for mining and research; they pay for themselves through growth in all other areas.
- Farming expeditions → Boosters that increase the number of groups and simultaneous expeditions directly result in more resources and rare raw materials (see How to Farm Expeditions).
- If you play for a long time and want comfort → Long-Term VIP (1 year): The daily antimatter and perks pay for themselves with a 35% return.
Common Mistakes
- Don't just grab everything. The great thing about flexible boosters is that you can use them precisely where you need them. Spreading them out = wasted currency with no noticeable effect.
- Buy a monthly VIP subscription and play for years. The annual return is 35% per month—you’ll actually end up paying more in the short term.
- Don't expect a direct boost to your loot from VIP status. VIP status is about perks and daily antimatter. Accelerators—not VIP status—provide direct benefits to your economy.
Frequently Asked Questions
How does VIP differ from accelerators? VIP is a subscription for a set period (1, 3, or 12 months) that offers ongoing perks and daily antimatter. Flexible Boosters are individual bonuses (resource gathering, science, expeditions) that you can activate one at a time to suit your needs. They’re different things—you can choose either one or the other.
Which VIP plan offers the best value? The longer you play, the greater the monthly return: 90 days yield an 18% return, while 365 days yield a 35% return (according to the game's code). If you play for a long time, a year yields the greatest savings.
What are the benefits of VIP membership? Every day—antimatter, a free daily bonus refresh, and additional promotions; VIP avatars; the ability to change your nickname color; the ability to post in the general chat while on vacation; and increased limits on intelligence storage and fleet sales.
What should you spend your money on first? Whatever supports your current goal: building up your base—accelerators for resource gathering and research; farming expeditions—accelerators for expedition groups and sorties; playing for the long haul for comfort—a long-term VIP.
