AirAttack HD vs Portal
AirAttack HD
AirAttack HD is an award-winning vertically-scrolling, top-down arcade shoot-'em-up where you get to assume the role of an up-and-coming ace pilot. Featuring an intense, bullet-hell-like gameplay, you'll get to fight against a wide variety of enemies while piloting a nice selection of unique aircrafts which you upgrade and customize to your liking as well. The game is a mainly single-player game and as such, it offers plenty of exciting missions for you to embark on, each of which has 3 difficulty modes. Aside from campaign missions, there are even arcade and survival modes for you to truly put your skills to the test.What makes AirAttack such a popular game though is not only because of its real-time physics and destructible environments, but also because of its intuitive combat which is delivered through a whopping 7 control types - Touch, Relative, Tilt, Joypad, Mouse, Keyboard, and Gamepad. Having a World War theme helps a lot as well!
AirAttack HD is a somewhat older mobile game though and as such, its graphics might not be comparable to its latest sequel, AirAttack 2, but overall, the original AirAttack is still a very entertaining game to play and it manages to hold up to today's arcade standards.
Portal
Portal is one of the most highly acclaimed and innovative puzzle-shooter game of all time. The game is set in the mysterious Aperture Science Laboratories where players, while playing as the human test subject, Chell, will need to manipulate objects and move through space by strategically opening portals to solve physical puzzles in controlled environments generated by the nefarious AI supercomputer, Glados.Featuring 19 levels in total that gets progressively more difficult than the previous, the game promotes creativity when it comes to puzzle-solving especially in the later levels, requiring players to explore various ways to best solve the level. There is also an advanced mode that drastically increases the difficulty of the last 6 levels. This is perfect for players who want to go a step further to challenge their puzzle-solving skills.
Portal is rather revolutionary in its own way and it's no wonder why the game has been awarded and nominated for multiple awards. If you fancy a fun and somewhat relaxing brain teaser, Portal is the game for you. Do check it out!
