If you like shooting games, this is another underdog you shouldn't pass up. Similar to the likes of rRootage, Warning Forever is a refreshing and innovative shooter that is very addictive - albeit very difficult. Naturally, each new boss is more difficult to beat than the last, with a lot more firepower and stamina. You gain seconds after defeating each boss. Instead, you have 120-second timer from which 20 seconds are deducted every time you die.
There is no defined number of ships in the game. These boss ships are drawn in 'abstract' funky style, and are automatically generated (using an algorithm not dissimilar to how swarms of enemies are generated in rRootage). To begin with, you don't battle countless hordes of alien ships in this game: only the "boss" ships, one by one.
Warning Forever packs enough innovation to set itself apart from other BulletML, however. Combined with the four distinct play styles the game has a lot of content that will last any shmup fan for a long time.Another superb freeware shooter from Japan, Warning Forever is similar to BulletML games like rRootage - addictive games that are turning "abstract shooters" into a new and exciting genre. There are 40 levels in Rrootage, and each one is broken into five sub-levels. This is the players only hope during some of the more manic bullet waves and the usage of the shield is most important. The shield will absorb all enemy fire in it's radius and after usage it needs to recharge.
As it is open source, it has been compiled for Windows, Mac, Linux, Android and iPhone. RRootage is an open-source, freeware bullet-hell game designed by Kenta Cho and released by ABA Games.
