Our take on The Sentinel
Players who want broad battlefield control may bounce at the single-cannon setup. The main wall arrives when balloons must be intercepted before reaching their height threshold while upgrade choices compete for attention between waves.
What is The Sentinel?
The Sentinel is a tower defense game built around a castle-mounted cannon.
The cannon moves with keyboard arrows and continuously launches spheres that fall under gravity toward rising balloons. Each balloon displays a hit value, and reaching a set height reduces the cannon’s life by that amount. Players begin each match by selecting one of 20 upgrades, then gain further choices whenever a charging bar fills. Upgrade decisions can favor stronger defenses, weapon improvements, abilities, or attacks suited to dangerous enemies. A match ends when the cannon’s life reaches zero or after surviving enemy waves for 15 minutes. Match points expand the starting upgrade selection over time, from 1 choice to a maximum of 10.
