Rush Royale - Tower Defense TD

Not for the base play but for some events.

the main screen is cluttered with limited time offers. Most of them aren't even really limited because even after the timers run out they'll just make the same offer later.

you can send or ask for resources needed to power up your units, but not a lot.

yes you can spend money to buy loot boxes to gain more units, and resources needed to power up your units. And while you can get some boxes for free, the better ones you need to spend money to get

technically? they're not a subscription thing but every month there is a thing that gives you rewards for getting points, and if you buy the "seasons pass" you get significantly better rewards. There are also more than one of these running at a time.

tho it is pvp so it's at least somewhat understandable

I don't but that's because I'm weird. But there is 100% a guild system designed to have that effect. Since theres a weekly guild tournament that each guild member needs to participate in every day to increase your chances of winning it, that tournament being one of the only ways to get the rarer loot boxes for free, so theres a lot of pressure to play everyday if you care about upsetting your clanmates.

the better units are something you need to buy. Or they'll give you one for free but you need to buy more of it to upgrade. The also have multiple point based reward seasons where you can buy a season pass to get significantly better rewards that are either difficult or impossible to get otherwise

you can technically get some with out spending a cent, but it's in such tiny amounts it'd take forever to gain a useable amount

there is pretty much no solo play, and very little co-op play
