There are many things wrong with this game.
1. This game has tiers, like in Robocraft, so you aren't supposed to be put with people who will annihilate you in one shot. However, I was put in a match with one of the top 10 players on the enemy team. They one-shotted me, and later, two others, on my team. To put this into context, destroying an enemy robot in this game can take over 10 seconds of non-stop fire.
2. As I mentioned before, this game has tiers. But you can only 'tier-up' when you upgrade your robot's parts. However, the only thing upgrading parts does is give them more health, except weapons, which get more damage as well as more health. This means, in higher tiers, your robot will have more health and do more damage. This also means every other robot will have more health and do more damage. What's the point? Am I missing something?
3. There is no progression in this game. Yes, you can upgrade your robot, but as I said, the whole 'upgrading' system is linear and useless.
4. There are very few people playing it. Getting into a match doesn't usually take any more than about 30 seconds, but being put into matches with, quite often, the same people, who are quite often, using the same robot each time, can get repetitive, especially when they use over-powered weapons.
5. You will occasionally get a box as a reward after completing a match. You can open these boxes with credits, the in-game currency, with a success rate as low as 0.25%, upto 5%. Failed attempts will not destroy the box, only the tools. You can alternatively pay real money in exchange for 'sparks', which you can use to open the box first time. This wouldn't be a problem if it weren't for the fact that these crates can give unique robot parts. That's right, people who pay real money get an advantage over those who don't.
Personally, I have enjoyed this game so far, but I simply cannot recommend it to anyone.
