Welcome Duzum,
It doesn't have to cost an arm & leg to get into but of course it depends how far you jump into the shredder ๐
My 2p worth adding to what Brophy said...
1) Yes, it is a bit more costly to rent first but it will save you lots in the long run.
It'll help you get a feel for the game and what gun style you'll want. M4, AK, long, short, etc.
And you'll certainly get to try other weapons people have.
If you buy anything before having UKARA it will be painted a bright colour (two-tone) If you then want to get rid of it, it will be worth less and harder to sell.
- AEG definitely the easiest and arguably most effective system. You can get AEGs with recoil for more realistic feel but obviously more expensive.
- Gas is the most realistic in operation and feel but more expensive to purchase and run. Can be problematic in Winter. But the big downside is you can't carry as much ammunition as an AEG with high capacity magazines. You will be at a disadvantage in a firefight. Gas guns (GBBRs) are more practical in a MilSim game where there is more emphasis on realism and more people use them.
- Co2 From my experience with a Co2 pistol. Expensive to run (including fixing leaks). Can't top-up on gas when low. Often shoot hot and hard to adjust power. To me not worth the hassle.
- No experience of HPA but not a fan because some get into it for stupid rates of fire ๐
2) Outdoor (woodland) uses more tactics and teamwork. Allows for a wider range of gameplay from camping sniper (hate em ๐), sneaky assaults to full on charges.
Not tried indoors (CQB) yet but from videos it looks fun though seems to often be starwars style shooting down corridors in stalemate. Faster gameplay with more emphasis on sprinting to get advantageous positions.
