Sky Force Anniversary: stage 9 last stage
Most addictive ever
Sky Force has an anniversary and reloads versions making it a trilogy. The game is a bit fuzzy about achievements but has lots of models, cards, trophies, and objectives. The reload version has 9 planes which you have to assemble by acquiring parts playing the stages. Cards and plan parts are dropped in the middle of a stage that you have to get away finishing the stage or miss it. Stars you'll collect from destroying enemies will let you upgrade your plane in 8 categories in the hangar. 4 Medals in each stage with 3 difficulty levels make 12 medals in each stage. To open the next stage you must complete the earlier one with a certain number of medals. Objective or prestige points will allow you to hire a better engineer to repair and upgrade your plan.
The game is utterly addictive and exciting to play. It needs serious attention to memorise every detail of a stage to cross it with medals. Some stages are difficult to rescue all humans to get a medal some to kill 100% enemies some with the other two. Anyway, the requirement of this game is to stay calm even when your screen is flooded with enemie’s bomb and others there is always a way out. When you face a boss you must know the drill and safe places. There are a lot of things here to master to get to the level I am in.
