Retribution is the sequel to Blacklight: Tango Down, which was released in July of 2010 and was panned by critics and end-users alike; suffering from unrefined gameplay and controls as well as a lack of content it failed to make an impression and was an all-around flop. Retribution hopes to remedy that, and for the most part it does. Movement feels tighter, gunplay feels more solid, and the game as a whole feels more well-realized than its predecessor. The current release isn’t without its problems—on my system Tessellation is broken and a friend and I have also experience some rather peculiar hit detection lag which has caused some impossible looking delayed deaths, but outside of that it has been more stable than not.
As of writing this, BLR sports several maps playable across King of the Hill, Domination, and Deathmatch/TDM gametypes. Microtransactions in the form of cosmetic and gameplay additions (weapons, attachments, stat buffs, etc.) are utilized to monetize the otherwise free game. There are a few items you can only get through paying, but the vast majority of them can be bought by spending experience points earned from playing the game, and if you’d rather not go through the grind you can opt spend cash to get what you want instantly. I have personally not spent any money on the game yet and have not felt like I’m at a disadvantage because of it.
It remains to been seen how much they expand on the base game going forward and if they tackle some of the technical issues in a reasonable amount of time, but if you’re looking for a F2P shooter I would certainly say you should give Retribution a chance. If they keep the game fresh with content additions and a stable player base forms this could be something to keep installed for a while.
