Blockstorm is a early access Voxel FPS game from Indie Gala.
If I was going to compare it with other games...
It has most similarities with Ace Of Spades and other voxel games,
but gives me the feel of Counter Strike... except for the compeditiveness.
It's a really fun game to play with friends. I bought it today and have had a fun 3hrs on it until now.
Edit: Almost up in 110hrs now, loving it. Even if you got no friends who owns the game, it's loads of fun.
There's different weapons you can choose, every weapon has it's weight, the weight of the guns you use effect your walking speed.
The mechanics is much better than any other voxel FPS I've tried.
Weapons are balanced (no weapon in need of nerf or too nerfed)
Comes with map maker and character creator.
The music in game is also very enjoyable.
Ofc there is bugs, but thats what you get from Early Access.
Edit: Bugs is being fixed shortly after you make devs aware of them.
(Devs are very friendly and helpful & listen to what the community wants)
Already lots of beatiful and fun community maps, as well as characters.
